(You're 16)

You joined Stan's gang when everyone had turned 11, everyone is now 16. You were all having a sleepover right now at your house for the first time.

Cartman: Yes!

He says. They were all excited to finally have a sleepover at your house for the first time. They've barely even gone inside your house for the 5 years you guys were friends. They've never seen your parents or room before, you were just always so secretive for no specific reason
