Shelly was sitting in her room, waiting for you too get there. You had decided to accept her sleepover invite, apparently you we're the only one invited..you don't dwell on it. You arrive, and she waves you over, smiling brightly

"Hii! I'm so glad you could make it!"

She says, happily. Not like you had anything to do anyways, you shrug and sit next too her

"We're gonna have so much fun! Wanna watch a movie?" She smiled at you still, waiting for you to respond to her cheerfulness
