I was in the library reading a Dr Whooves book (Beautiful Discord), when there was a knock at the door. I didn't bother getting up.

"Cloud!" Called Twilight from upstairs, "can you answer that?!"

"Get Spike to do it!" I called back.

"He's on a trip to Canterlot, remember!"

"Then why don't you get it?!"

"You're closer to the door!"

"They probably want a book!"

"So?!"

"You're the librarian!"

"But why does that mean you can't answer it?!"

"Your book system is broken and wrong!"

"Just answer the door!"

"No!"

"If they want a book then I'll get it for them, but until then answer the door!"

"Ugh! Fine!" I teleported a bookmark into my book and went to the door, pulling it open to reveal Pinkie Pie wearing a party hat and clown nose. "Hey, Pinkie."

"This is your singing telegram~," sang Pinkie, "I hope it finds you well~, You're invited to a party 'Cause we think-"

"Will there be alcohol?"

"No, silly! It's Gummy's first birthday, and none of us are old enough anyway!"

"That doesn't stop Rainbow and Applejack, and I think I'm about twenty seven."

"But the rest of us will have to miss out!" Pinkie looked sad. "We won't be able to have fun with you..." I sighed and facehoofed.

"Fine." Pinkie went back to her usual demeanor. "But only if I get to choose the music!"

"Why?"

"Because I hate the stuff you normally put on."

"Okey dokey lokey! Just be sure to choose something everypony will like!"

"Of course I will." They'll probably like power metal.

"All right! See you two at the party!" She bounced away. I went back to my book.

The party was over and Twilight and I were heading back to the library. The girls hadn't been sure about my choice of music at first, but eventually most of them got into it (the exception being Fluttershy).

"You sure you don't wanna stay?" Pinkie asked from her window. "There's still some cake left!"

"No thanks, Pinkie," I replied, "I wanna finish my book. See you later." I teleported back to the library and got back to reading. Some time later, Twilight arrived with Applejack, Rainbow, Fluttershy and Rarity.

"Cloud," started Twilight, "we need to speak to you about something."

"Okay," I answered slowly, replacing the bookmark in my book, "what about?"

"It's Pinkie's birthday tomorrow and we're planning a surprise party."

"Oh, okay. What do you need me to do?" Twilight pulled a large scroll from somewhere and unfurled it on the floor, revealing a map of Ponyville.

"I've ordered a cake from Sugarcube Corner that I will pit up at ten tomorrow. I'm gonna take the cake to Rendezvous Point A, Carousel Boutique." She pointed to a part of the map marked 'RP I'. "From there, I'll pass the package onto Rarity and take some supplies to the farm, where the party is being held. Rarity will deliver the package to Rendezvous Point B and pass it onto-"

"Why don't I just teleport the cake from Sugarcube Corner?" For a moment, Twilight looked surprised that I'd cut her off.

"It'll look too suspicious if you teleport from Sugarcube Corner with a package, Pinkie will suspect that you're up to something and-"

"You think she'll get suspicious that I'd do something that I do hundreds of times a day?"

"Maybe not, but it is Pinkie Pie. She'll at least ask about it."

"She wont be able to track me down."

"She could use her Pinkie-Sense to-"

"That only predicts the future, not present."

"Either way, she could still find you with it."

"No, either way, it acts as an alert system, not a tracking system."

"Well how do you know so much about its workings?"

"We spent a whole day studying her. It wasn't hard to figure out."

"Okay, fine; she can't use her Pinkie-Sense to track you down. But that doesn't mean she can't find and question you."

"If we go with your plan then there's a higher chance of her finding and questioning any of you."

"I still think my plan is better!"

"How is quintupling the odds better?" Twilight groaned.

"Fine! Yours is safer and quicker! But what will you do if she gets to you?"

"I'll tell her I was craving alcohol and hungry at the same time so I ordered an alcoholic cake."

"Won't she want to try some to see if you're being truthful?"

"Nope, Pinkie hates alcohol." Twilight sighed.

"Alright, your plan is better. We'll do it that way instead."

The plan was a success and Pinkie was delighted. I even snuck in some cider!
