There was a knocking at the door.

"Applejack dear. Would you mind getting that." said Rarity, gesturing towards the door.

"Fine." said the farmpony, huffing slightly.

Opening the door Applejack saw Twilight practically beaming at her.

"Hello there Twilight." said Applejack.

"Hi AJ." said the alicorn. "I'm afraid Rainbow Dash and I will be unable to come to dinner tonight if that's okay."

"Sure thing Twi'." said Applejack.

"Oh good. See you later." said Twilight, turning around and bouncing along the corridor.

Applejack sighed, wondering what could have come up. She closed the door and made her way back into the bedroom.

"What was that all about?" said Rarity.

"RD an' Twilight aren't coming to dinner tonight. No idea why." said the farmpony.

"Ooooooohh!" squealed Rarity jumping off her bed. "Rainbow told her!"

"What is it?"

"Can't you tell?" said Rarity looking funnily at Applejack.

"No. The way I see there ain't much to tell. They ain't comin'."

"Exactly. Because they're going on a date."
