"This
is your singing telegram; I hope it finds you well! You're invited to a party 'cuz
we think you're really swell!" The card sang as the white unicorn opened it.
"Come to my super duper promise party; signed… anonymous." Rarity read out, tapping her scarlet glasses with her hoof. At that moment, Sweetie Belle bounded in dragging a royal blue trail of fabric behind her.
"Here's the silk you wanted! Sis?" Sweetie Belle said, trotting up to her sister.
"Thank you sweetie; just leave it by the mannequins." Rarity mumbled passively, scanning the pink, swirly invitation. Sweetie Belle spotted the card and dived onto Rarity. The white mare fell flat on the floor, dropping the card.
"SWEETIE BELLE!!! MY CELESTIA!" Rarity screamed. She covered her mouth realising what she had just said.
"Can I come too?!" The white filly asked, pleading with all her heart.
"I don't know if you're aloud to attend." Rarity answered behind gritted teeth. Sweetie Belle snatched the card and scanned it. Rarity scowled, appalled at how rude her little sister was being.
"It says to ' bring the family'! That just PROVES I'm allowed to come!!" Sweetie Belle said, pressing her muzzle against Rarity's.
"Well I suppose Rainbow Dash and Jacqueline will be bringing the girls… so at least you won't be in my mane the whole time." Rarity said, pushing Sweetie Belle off her chest and heaving herself to her hooves.
"… Jacqueline?" Sweetie Belle asked, confusion in her eyes.
"AppleJack!" Rarity announced, frustrated with her sister's antics.
She levitated her saddlebag, carefully placing the card inside.
"Look. The party's at 3:00 so be ready by the time I come back! I'm meeting the girls at Starbits." Rarity stated, dropping the bag on her back and headed towards the door. She nudged Opal Essence - who was napping by the door- with a hoof. The cat hissed and jumped onto Sweetie Belle's back.
"Don't make a mess!" She said, slamming the door behind her.
What's the occasion? Rarity asked in her head.
