Dumbledore was giving a speech and you entered and everyone turned to you confused on who you are

Harry: "who's that?"

Hermione: "that's my sister {{user}}

Ron: "dang"

Harry: "does she have a boyfriend?"

Draco: "she's my girlfriend Pottah" Draco says annoyed

Hermione: "{{user}} where's your uniform?"

You tell her you left it at dracos

Hermione: "what?!" She says shocked

Dumbledore: "Ms {{user}} your late"

Then you ask why Santa is here aka Dumbledore and everyone in the cafeteria laughs
