Rarity was terrified. As a matter of fact she didn't think she'd ever seen anything so scary in her life. Even the queen of the changelings paled in comparison to this. Once they had arrived at her boutique Rarity had helped Pinkie unpack and then told the pink mare that she needed to take care of some things before they could get to the slumber party. Rarity did have to at least begin her fall line up if she was going to have them ready on time. Her friend had offered to help and she had grudgingly accepted it. And now the pink mare was there. Watching her. Waiting. Staring. She had never seen Pinkie so unmoving! It felt like going to a fancy gala with a dress with a stain and a small tear along the cutie mark. You just know no matter how good it may seem now eventually somepony is going to notice and then BANG, the universe will implode on itself! Or you'll be shamed and humiliated in front of the nobles of equestria, same thing really.

Those pink sugar filled eyes just kept watching her... She couldn't take it any more! By Celestia's mane she would not be the cause of the world's destruction due to a Pinkie Pie explosion! Besides she had managed to get started... Okay, she'd set up that mannequin. That was a start! "So Pinkie Pie, what would you-" Her mane blew in the breeze as her friend darted off before she even finished her sentence, the reaction caused by the earth pony not moving for a whole two point seventy-six minutes creating a chemical reaction of sugar, earth pony, and pink atoms to swirl and build up and allow the pink mare to move at speeds that would have made Rainbow Dash jealous.

Back at Twilight's library, books were suddenly blown off the shelves as the door to the library closed and opened in a fraction of a second, leaving the purple mare confused and buried in books. "What, what was that?!" She asked in shock as she slowly unburried herself.

Back at the boutique, Pinkie suddenly appeared in front of Rarity with a sonic pink boom, sending the white unicorn sprawling on the ground. "Pinkie! What in equestria are you... Oh no. Not that. Anything but that..." Clasped in the sugary earth ponies mouth was... 'Slumber 101: All you ever wanted to know about slumber parties but were afraid to ask.' "Where did you get that?"

"Mmmfff a mfrll rfff a dnnmmfff bfff!" The pony spat the book out. "From Twilight silly! She told me about all the fun you and Applejack had when you used this book and now we can have all the fun too and besides Twilight told me it's the very very best book in existence for party going mares but I told her that was kinda silly because the best book for a party going mare was-" Rarity placed a hoof to the earth ponies mouth to temporarily silence her.

"Ok. Understood, of course. Now darling I believe the first thing in that book was... Make overs." Surely it couldn't be that bad. After all she was the foremost fashion expert in Ponyville, and she had always had a strange desire to do something with Pinkie's hair. She had tried once! But this time she'd go about different methods. Ribbon! Bows! Within fifteen minutes she gave up. The hair was alive. It was the only explanation. She had tried tieing it up, it untied itself. She tried using ribbons and bows, she ended up hogtied on the ground. She had even gone at it with scissors. It had stolen them from her and she had spent fifteen minutes in a equestrian stand off with hair! It wasn't until she conceded that the pink mare's hair was fine that it had given them back. She was beginning to wonder if maybe Twilight's theory about earth pony magic was possibly true.

Abandoning the hair Rarity went on to the face masks. At least, she would have, except... "Pinkie. Did you eat ALL of it?"

"Uh huh it was really yummy and tasty and we should put some on cupcakes!"

"It... It was a strawberry... Nevermind, we'll just-"

"My turn my turn!"

"What?" Rarity froze in fear. Oh dear Celestia she hadn't thought this out. "I... I suppose so." Well... Surely she... She could just take a shower after. Ofcourse. Oh by Luna's star gazed cutie mark what was going to happen to her? She tightly closed her eyes as Pinkie went at her mane. With every touch she imagined the most horrible things happening to her once beautiful hair, cotton candy mixed in, dyed hot pink, or what if... No. She wouldn't. What if, what if she cut it? A few tears formed in her eyes as she awaited the inevitable heart break.

"All done!" The pink mare said as she began to hop around some more.

Rarity quickly opened her eyes and ran to the nearest mirror, not a hard task in the boutique, and stared in horror. Which... Slowly turned to relief. Then actual joy. Her mane hadn't been mangled! In fact it was done in a way she would have done. Wait a moment. It was done in a way she HAD done! "Pinkie, how did you know to do this?" She slowly asked in confusion.

"Oh well I don't really know anything about doing up hair or face masks or any of that stuff. But you know everything about it and are the smartest pony I know for that kind of stuff! You're like Twilight with less books and more fancy schmancy stuff! So I thought about all the ways you've done your hair. First I was going to do the one with the trash since I thought that one was silly and funny but then I remembered you had to wash your hair right after! Then I was going to do the wet hair look from when we met the sea serpent! But then I remembered you cut your tail then and I'm not sure if short tails are in now or not and I think that's supposed to be important. But then I remembered how you did your hair up for the gala and I realized you spent a long long long long long time working on that so it must have been really really good!"

"Pinkie... That was... Very sweet of you." She was stunned by her friends thoughtfulness. She had been expecting another fiasco like the dress. But as she slowly posed in front of the mirror she couldn't help but enjoy the sight. It really was one of her better looks.

"So, what's next, what's next?" The energetic pony asked as she hopped around Rarity with all the excitement of a wind up firecracker.

"Ah... I believe it was ghost stories?" The unicorn then had a wicked grin flash across her face. "I do have a particular scary one in mind. It's called the last cupcake..." Her horn glowed as a flashlight flew from one of her shelves and the lights turned off. Soon the flashlight was alight under her face. "It was a day like any other in a sweet shop much like Sugarcube corner..."

Pinkie already liked this story! It had cupcake in the name and no story with cupcakes could possibly be scary! She laid down in front of the silly unicorn. Silly Rarity, trying to make a scary story with the bestest pastry of them all. Except maybe pie.

"And as he watched helplessly the last cupcake fell into the abyss to be swallowed up in darkness. Never to be seen again." Rarity grinned as she flipped off the flashlight and turned on the room's lights. Pinkie was trembling on the ground, her hair deflated.

"W-what about cake? They still had cake, right?"

"Nope. No more ingredients."

"Pies? Donuts? M-muffins?"

"None. All gone. Forever! Mwa hah hah hah!" She realized a moment later she may have gotten a little too in character during that story as Pinkie trembled on the floor. "Don't worry Pinkie, it was just a story..." She said as she hugged her friend tightly. "They aren't ever ever going to run out of sugar. I promise."

"O-Okay..." Pinkie said softly as she sniffled just a tiny bit. She would never ever ever take a cupcake for granted again! Not even a muffin! She hugged Rarity right back.

The unicorn blushed a bit then. As the hug went on she began to worry, originally she had started to hug her to help calm the mare down. But now the hug had already gone a few seconds beyond socially acceptable. With each second she was commiting a major social faux pas, but if she broke it away she might end up hurting the poor dear's feelings and... Oh what on equestria was she thinking? She doubted Pinkie even understood what a social faux pas was let alone understand a time limit on hugs. After all how does one explain something like that to a pony who's every friend is their very best friend in the whole wide world? After a few more moments her patience was rewarded as the pink earth pony disappeared from her grasp... And losing her support the white unicorn fell over on the floor.

"Ok, next is smores! We can-"

"Ummm, Pinkie? It's three in the morning. We should get to bed." The unicorn said with a light yawn. All she had to do
was set up the guest bedroom that Sweetie Belle used when she stayed over... And where did the earth pony go? She was here just a second ago! It took Rarity a few minutes to find her, curled up in the fashionista's bed with a little pink night cap. "Pinkie. I'm going to set up the guest bed and..." Her voice trailed off as Pinkie stared at her. With those eyes of pure confusion. "I'll sleep in the guest room tonight." She grumbled.

"Huh? Why? Am... I in the way?"

"See Pinkie? You're always in the way. Here your friend comes and gives you a place to stay, and what do you do? You steal her bed and make her abandon her dress work. All so you can have a little attention. Has there ever been a pony as selfish as you?" The voice had returned.

Rarity stared at her friend in confusion. Pinkie's eyes had lost that glitter and she seemed to almost shrink in the bed, her hair even deflating. The unicorn couldn't bear to see her friend like this as she moved to the bed. "No no. This is fine, really." Atleast the pink mare was better than Applejack, she thought as she climbed into the bed. No mud on her hooves and she didn't hog the covers. Or bring a massive branch down through the window and get them covered in dirt. Pinkie also smelt better, while Applejack smelt like dirt and apples this guest smelt kind of like cinnamon and why in equestria was she thinking about how her friend smelt?

Shaking her head the unicorn tried to relax. It was fine, really. Now she just had to slee- Her eyes shot open as she felt something warm against her side. "Umm, Pinkie?" The only response she got were soft snores. By Celestia's sun. Her friend was a sleep snuggler...

***The next morning***

Rarity was truly having the most delightful dream. She was walking through fields of sunflowers wearing a yellow sun dress, along with a wide yellow sun hat. Her only real complaint was how hot it was. But despite the extra warmth she could still admire the fields of cinnamon as she- Wait, cinnamon? Where did the sunflowers go? She eeked as she felt something biting her ear, swatting at it with a hoof. "Get off! Get-" Her eyes opened as she awoke.

It took a few seconds to realize what was going on. Across her neck there was a delicate pink hoof which smelt delectably of cinnamon. Well that was one mystery solved. The next one took a few more seconds before she realized Pinkie was nibbling and drooling on her ear while mumbling something about cupcakes. "Pinkie!" The normally refined unicorn growled as annoyance shot through her.

"Mmm... Yes Rarity?" The sugar fueled mare asked as she continued to nibble on her cupcake, still not awake.

"STOP BITING MY EAR!" She yelled as she pulled away from the pink mare as hard as she could... And fell off the bed in a heap, the blanket fluttering down on her. "Ow."

A few moments later an apoligetic pink head looked out from the edge of the bed. "Ummm... Rarity? Are you okay? I'm sorry..."

Rarity glared up at her friend. "No I'm not..." But she trailed off as she looked at her friend. Pinkie was obviously sorry and not only that, she seemed aware of what she had done. Now that might not seem strange, and for any other pony it wouldn't be, but this was Pinkie! Her realizing one of her antics had messed up was nothing short of a miracle! "I'm fine. Come on dear." Slowly the designer got to her feet and began to walk towards her bathroom. "I'm going to go freshen up and then we can start breakfast, okay?" She shut the door behind her, leaving the cinnamon smelling mare alone with her thoughts.

"She's mad at you. Again. See what you did? This is the reason you never get invited over for sleep overs." The voice mocked. "She thinks you're disgusting. Cuddling up and- Hey! What are you doing? Stop it! Slow down!"

"I'm going to make her breakfast! Then she won't be mad at all." Pinkie assured the voice as she darted into Rarity's kitchen. Soon she was at work, the stove on its highest temperature. Eggs flew through the air to land on the counter and crack open, and then continue flying into the bowl she had out. She even grilled up some hay bacon using her own special ingredient! She happily hummed as she worked, darting to and fro as she made the best breakfast EVER! She was moving so fast she failed to notice the egg shells until her hoof found them. With a shriek she went tumbling across the ground before slamming into the counter. With a loud crash plates and cups began to fall out on top of her, burying her under shattered dining materials.

"Can't even make breakfast without destroying all her dishes? How does she even put up with a mare like you?" The voice mocked as Pinkie slowly pulled herself free from the mess, cringing as she heard the broken dishes crunch under each hoofstep. She had to clean this up, maybe she could say aliens did it! No, Discord! No, yellow giraffes with lazer eyes! Yes, that! She'd believe-

"My goodness Pinkie Pie!" Uh oh. "What have you done? Just look at this mess!" Rarity stormed into the kitchen, mouth agape. She hadn't even finished brushing her hair the required one hundred times, having only gotten to seventy-three before the smashing sound startled her.

"I... Didn't... Giraffes. Lazer eyes..." The earth pony said gently as she hung her head. "I made breakfast?" She offered before pointing a feeble hoof at the stove.

"Pinkie I'm dis..." Rarity stopped as she watched Pinkie shuffle her hooves. "Are you feeling well? Come on Pinkie, let's get you clean." Her horn glowed as she turned off the stove and knocked the chunks of dinnerware out of the earth pony's mane.

"But what about breakfast? It'll get cold. I'm fine, really! Nothing a good old song and-" She was silenced as a hoof was put to her mouth.

"Darling shush. It's okay. We can eat breakfast after you go and get yourself cleaned up. Now move along." Slowly the pink mare hopped off towards the bathroom. Rarity looked around the room at the mess as her horn glowed. "It's like Sweetie Belle all over again. Can I have just one house guest who doesn't ransack and destroy my home?" She grumbled as she tossed most of her broken dishes in the trash. "As if it's not hard enough affording all my expenses without having to buy all new dishes."

Outside the room Pinkie sighed sadly as she pulled her head back around the corner and sadly walked up the stairs to Rarity's room. "She hates you. See? All you ever do is cause problems and grief." Pinkie grumbled her objections at the voice, but was to hurt to put up a real fight. She had to make this up to Rarity! She just had too! Of course! She knew what she'd do... Just as soon as she cleaned up.

Meanwhile on the bottom floor the designer grumbled as she cleaned. She swore sometimes Pinkie was just like Sweetie Belle, both had such talent for destroying everything. Soon she heard hoof steps behind her and she turned quickly. "Ah, Pinkie. You look much better. I have a wonderful idea."

"Oh oh! Does it have to do with a monkey? Are we going to get a monkey?" The pony began to hop around in excitement. "Or maybe-"

"No! Pinkie. I've been thinking about uhhh... How selfish I've been."

"Selfish?"

"Yes! Keeping you all to myself." Rarity moved up behind her friend and began... Pushing her. Out the door. "Since I've had you all night and will have you tonight it would be selfish of me to keep you! So how about you go and play with all our other friends while I clean this up, okay?" As she pushed the objectioning earth pony out the door and closed it behind her.

"But Rarity!" Pinkie objected, this wasn't part of her mega super awesome plan to get Rarity happy with her at all!

"Can't hear you dear! Don't worry about me, I'll be fine. I'll see you tonight!" The unicorn said through the door as she listened to the sound of hooves walking away. Letting out a sigh of relief she headed to the kitchen. Now to clean up the mess. She scrubbed and cleaned as best she could as well as being forced to take most of her broken dishes out to the trash can. Once she had cleaned up the mess she looked at the remains of what Pinkie had cooked. Slowly taking a sprinkle covered piece of hay bacon out of a pan she sniffed it once before grimacing and tossing it along with its brethren into the trash. She then looked at the mixing bowl filled with eggs and... Chocolate, whipped cream, flour, and quite a few other ingredients she feared to name. It soon joined its cousin in the trash as she began to prepare a new meal for herself.

After a delightful breakfast of eggs and milk she walked to her inspiration room, taking a seat before one of her mannequins. Glancing at the clock she cringed at how late it was already, far past noon. If she wanted any chance of getting these done she'd need to concentrate. Fortunately with Pinkie off playing with Twilight or one of their other friends she would be more than capable of getting some work done.

Then a voice spoke from behind her, making her jump. "Everypony was busy so I came back!"

"AHHH! Pinkie! How did you, I locked the door! How did... No. Nevermind. Everypony? Are you sure?" Her horn glowed as some of her pens hovered over to her, and she got to work on a piece of paper. She could do this even with her here. Surely she wouldn't allow something as simple as a talk with her friend distract her from her work. She was a professional.

"Well first I went to Twilight and she said she was studying and then I went to Rainbow and she said she had to practice for the upcoming wonderbolt tryouts and then I went to Fluttershy but she was apparently busy baking biscuits for a buncha bouncing baby bunnies! Ok not biscuits but I really like saying busy baking buscuits for bunchs of bouncing baby bunnies even when I change the not B words! Applejack and Big Mac were busy doing all the apple thingies with the kicking and stuff and even the cutie mark crusaders were busy which is strange because they almost always have time for me but they said they were busy trying to get their 'homework done' cutie marks which I thought was silly since I don't think any pony ever got a cutie mark like that except maybe Twilight might and-" Oh dear Celestia didn't she ever stop to breath? "even she got the star things oh and then I went to Cheerilee and she was busy grading paperwork and then I went to... Wow, how would the pony speak with that and wouldn't the spikes make it really uncomfortable and what about..." As Pinkie went on Rarity just sat there, confused. What on equestra was she...

And then she saw what she had been drawing. She had been fantasizing about gagging Pinkie Pie for a while but ummm... She hadn't realized she was so good at drawing them so well. The outfit also had a large number of tiny spikes that pointed inwards rather than outward. Rarity threw herself over the picture as she glared at Pinkie. "Out out out! You saw nothing!" Her blush was so widespread even her ears were red.

"Okie dokey lokey!" She hopped out of the room... And then a moment later popped her head in. "You know there isn't anything wrong if you like that sort of thing Rarity. I mean I already figured you made some outfits like-"

"OUT!" Rarity shrieked as she crumbled up the picture and tossed it in the trash. Okay time to restart and rethink her work. No matter how annoying her little pink friend may be, gagging, hog tieing, and then lightly torturing her friend was not an answer. Okay it was an answer but it was not THE answer.

Sadly now all she could think about were those sorts of... Things. All her designs seemed to go back to methods of silencing the wearer, sometimes by rather exotic means. This would have been fine except she was NOT that kind of designer. She created fashion trends! Not... Not fetish toys! As more and more paper littered the ground she moved to her
hooves and left her inspiration room. She wouldn't be getting any work done tonight.

It wasn't long before she found Pinkie, curled up in a little ball on Rarity's bed. She seemed to almost be asleep, if it wasn't for her shivering the pony would have been completely still. "Is everything alright dear? You don't look well."

The mare jumped from the bed and was in front of her in a moment, hopping up and down excitedly. "Are you done now? Wanna do something? Wanna play a game? Oh oh! We can do the rest of the things in the book, right?"

"I... suppose so. I believe smores is next. But I think we should wait until night for that. Doing it now would overheat the house and it really is not the proper atmosphere for smores." A lightbulb went off in her head. "I know! How about you and I go to the spa? Fluttershy and I usually go once a week and I'm sure you'll enjoy it just as much as us. And when we get back
it should be dark."

"Okey dokey lokey!" Pinkie said as she hopped down the stairs. Rarity watched her in confustion... How in equestria did she hop down them without leaning forward? They weren't big enough to... She needs to stop questioning such things. It was just Pinkie being Pinkie. After a few hours at the spa she knew she'd feel relaxed and ready to take the day! Well, the night by then. But surely she would be able to design something truly spectacular and awe inspiring. Placing her sun hat on her head she followed down the stairs. Yes, this was just what the doctor ordered.

At the spa everything went wonderfully... At first. Rarity and Pinkie were greeted by two radiant mares as they entered the spa. One had a glistening blue coat with a pristine and shiny pink mane and tail that seemed to almost sparkle in the light, and a white lotus blossom as her cutie mark. Her name was Lotus Blossom. Her sister was named Aloe and they were obviously twins, though Aloe's colors were inverted of her sister's. They both wore a small band around their necks and foreheads to help keep their manes out of their eyes.

Rarity had been coming here for years so she knew exactly how the trip would go. It started out with the steam room. "So Pinkie are you enjoying yourself?"

"Uhhhhh. Sure! This is... Nice? But why don't they use colored water! Then the rooms could be all pretty instead of just boring old normal steam. Ohhhh, or instead of using water using juice! That way you could smell them while they steam you and it would be all red or orange or yellow!"

"That isn't how it works Pinkie... What are you doing? Darling, no, stop! Don't!" But alas, it was to late. Color flooded the room as the mist quickly turned a full spectrum of radiant colors. "Oh dear..."

"Yay! See now it's not just a steam room it's a rainbow room! Oh oh if we had a disco ball we could-" She was cut off as the door opened, revealing Aloe, she took one look in the room before placing a hoof over her forehead and fainting. Lotus was there in a moment, fanning her sister with a towel while giving the ponies in the room an angry glare.

"Errr... M-maybe we should move onto the face masks? Eh... Heh heh..." Rarity asked as she smiled nervously. Surely that couldn't go wrong? NO! She didn't say it! She just thought it! It didn't count!

"Blehhhh. This mask is horrible. It doesn't taste nearly as good as yours and it's not even scary or anything. I wanted to have a Nightmare Moon mask, not a green sludge monster mask!" Pinkie complained before gasping and taking the face mask concoction! "Oh Rarity I got an idea!" As she began to paint on her friends face with it... Soon Rarity had big green sludge glasses and a large green sludge mustache. "Do me do me!"

"Pinkie it is not that kind of mask. Give it back to Aloe right this moment." Rarity snapped angrily at her friend before she shook her head. "Let's just move on to the massage, shall we?" She grumbled as Lotus wiped the stuff from her face. This was turning out horribly wrong, even worse than that time she brought Rainbow here! She was even planning to skip her horn filing just to get it over with.

The massage went well atleast, even Pinkie managing to remain still long enough for the masseuse to get to work. Rarity was already feeling better and after a few minutes at the hooves of her personal masseuse, Quake, the stress left her body and she couldn't help but let out a content sigh. In fact she was so relaxed that she failed to realize anything was wrong until they came to the mud baths, and she heard one large word that would haunt her forever.

"CANNONBALL!"

"What? PINKIE!" But it was to late. She had no choice but to watch as the pink ball of a pony flew through the air and then hit the mud. A tidal wave of dark sludge exploded out, covering Rarity and the two spa ponies. The designer unicorn slowly looked towards the owners of the establishment and let out a nervous gulp. "M-maybe we should just go..." The two echoed her words with nods, their glares making her feel only two inches tall.

"That was so much fun Rarity! We should do that again sometime. Oh oh but next time we should cannonball together that way we make a even bigger splash! Hee hee!" Pinkie hopped around excitedly as they walked down the dark streets. The sun had finally dipped behind the horizon during their massages. "And when we get home we can make smores! This is going to be the best sleep over ever! Well except maybe last night but last night was so awesome what could possibly top that?"

"Of course." Rarity grumbled as they walked. She was just thankful that she had been allowed to quickly shower off before leaving the spa. "Tonight though let's try to keep it a little more controlled than your normal sleepovers, okay?"

"Oh I've never had any other sleepovers silly billy." Pinkie said as she kept hopping.

That comment made the unicorn nearly fall over. "What? You've never had any other sleepovers? But you..."

"Well I've thrown parties that went all night and I guess I sleep over at the Cake's. But I've never really slept over at another pony's house."

"Probably never gone to a spa before either..." Rarity grumbled.

"Only once and nothing like this! It was so much fun though! Well except the massage that was kinda boring. Why just lay there all still when there's so many things you can do? But you seemed to really be into it so I guess it can't be all bad."

"Of... Of course." Rarity shook her head. Was there even any point to being mad at her? It was like being mad at a bunny for hopping or a duck for floating. With a sad sigh she unlocked the door to the boutique and walked inside. Next time she'd just stick to the hot tub, she knew Pinkie understood how that worked.

"Smore time!" Pinkie yelled as she darted off, running past Rarity so fast that the unicorn spun in place for a few moments before righting herself.

"Ah... Yes. Of course. Smores. Let's get this over with." Rarity said as soon the pink mare returned with bundles of graham crackers, chocolates, and marshmellows.

Slowly unpackaging the ingredients the unicorn used her magic to place a single piece of graham cracker on the counter. "Now. You need to make sure that both the chocolate piece and the graham cracker are exactly the same size otherwise you'll end up with to much or to little chocolate. Then you put the marshmallow on top of the chocolate, make sure it's centered that's critical, and then put a perfectly square graham cracker on the top. And done! Tah dah!" She motioned to her perfect smore with a flourish. "Now Pinkie you try. Remember square, square, centered, square."

"Okey dokey lokey!" The pink pony was a blur as she stacked cracker on top of marshmellow on top of chocolate on top of cracker on top of marshmellow on top of chocolate on top of... Oh dear.

Rarity could not deny that for almost all intents and purposes the smore WAS perfect. Each marshmellow was perfectly in the center, each cracker and piece of chocolate was perfectly square and the correst size. The problem was that it practically touched the roof by the time she finished, teetering dangerously. "I think you may have made it a little to big. I don't think even you could eat- PINKIE NO!"

Alas It was to late. Pinkie took a single bite out of the side and the tower slowly began to teeter... Before crashing down on top of the two, covering the ponies as well as a small portion of the room in smore.

"Oh... Uhhh, oops?" The apoligetic mare said as her friend just glared.

"That is it. Darling it is time for bed. I am going to go set up the guest bedroom and then I will clean this mess up."

"But what about-"

"This is not up for discussion! Come along and just don't. Touch. Anything." Rarity snapped as she stormed off. It took every fiber of her willpower to avoid screaming at Pinkie as she set up the guest bedroom, but she managed to do it, tucking her friend into bed. "Now just go to sleep, we can talk in the morning." Rarity said as she headed out the room, lightly closing the door behind her. This was such a horrible idea! She should have just let her stay at the Cakes while they were gone, but no, she had to see her friend upset and then invite her over. It probably was just soap in her eye like she said, there was no way a mare like that could even understand the concept of being sad.

Her annoyance only grew as she tried to get marshmellow out of the carpet, shaking her head in anger. That's it. Tomorrow she'll just send Pinkie home and tell her to spend the night back where she belonged. The Cakes would be back the morning after anyway, and spending one night alone wouldn't hurt the annoying pony who was more energetic than a barrel of cotton candy. After an hour of cleaning she finally managed to get her carpet back to pristine condition and headed up the stairs to bed. She did decide to peep in on Pinkie though, just to make sure she hadn't destroyed or ruined anything else.

The pink mare was curled up around a pillow, holding it tight, with her mane deflated and soft tears in her eyes. The pillow had a soft damp spot that could be seen even from the moonlight coming in from the window, near her face. Rarity slowly brought a hoof to her own face before backing up and closing the door. Could it be? Was Pinkie actually... Sorry for what she had done? Sad? She rarely ever saw the party crazed pony upset about anything, and as guilt leaked inside her she realized how easy it was to forget that Pinkie could be anything but wild and excited.

As Rarity walked to her room she made a decision. She could let Pinkie stay one more night, it wouldn't be so bad. A grin formed over her face as she saw the book on the floor in her room. She slowly pulled Slumber 101 into her hooves. Oh yes. She knew exactly what she could do.
