Pinkie Pie´s eye was twitching. It wasn't her Pinkie Sense at work, mind you. It was the consequence of repressing all her natural instincts, of holding back her body from jumping into the ceiling and her hooves making her dance around. And how could she not do it when a pony was playing the piano in front of her? She wanted to dance and sing so badly but she wasn't supposed to move. She wasn't at a party, it was...umh she couldn't remember what name Rarity sued but it was one of those fancy names that sounded like a delicious cake.

“That Frederic is such a delight. Such a handsome stallion,” a fancy mare mentioned to Rarity.

“I was just saying the same thing to my friends, isn't that right, Pinkie dear?” Rarity asked and she noticed Pinkie´s twitching eye. The other pony noticed too so Rarity faked a laugh and whispered to Pinkie. “Pinkie Pie, you Pinkie Promise to behave.”

“I am! I´m standing still just like you asked but…”

“You better do! You insisted in coming to this event and that means respecting the proper etiquette, do you understand?”

“I do but…”

“That means no singing, no dancing, no humming and certainly not jumping into stage.”

Pinkie Pie sighed and nodded. “I promise, Rarity. I...I won't do a thing.”

Rarity seemed pleased and returned to the other mare. Pinkie Pie took a deep breath and lock herself in position. If she endured a full hour watching paint dry, she could endure this event. She just needed to concentrate on doing nothing.

Somorhwoe she amnged to remain in postion for the rest of the concert. The pony stopped playing and bowed to the audience who politely applauded.

“Well, dear. That wasn´t so hard, was it?” Rarity said, patting Pinkie on the back.

This caused the now purple pony to release all the contained air and she fainted. Rarity had to fake another laugh to cover for her unconscious friend.

****

“Absolutely not! I´m not goign out!”

“Oh come on Rarity, you Pinkie Promise!”

“I know I did but that was before you show me this...this...gah, I can't even call it an outfit! It´s so...ewwww!”

“Rarity…” Pinkie saying the unicorn´s hooves. “Do you love me?”

“Wha-what is this all of a sudden?”

“Rarity…” Pinkie said, sporting her best sad puppy eyes.

“O-of course I love you! You're one of my best friends and I care deeply for you…”

“So…” Pinkie said, blinking a few times.

Rarity did her best to fight it but she was ultimately defeated. “Fine,” she said, sighing.

“Alright everypony! Are you ready for the spectacle of the greatest clown duo of Equestria?” pInkie Pie shouted, dragging Rarity along.

Rarity somehow managed to blush so hard that both her makeup and white coat turned red. This only made the ponies laugh harder, especially Rainbow who was even more excited that the birthday guests, Pound and Pumpkin.

Rarity managed to sigh one more time before the first pie hit her face.
