Annoying “Friends”

So there’s this girl at my school who’s so immature. Where in 9th grade, but she acts like she’s in 2nd 24/7. She says MOOO like a cow every time she spots me in the hallway. She try’s to wipe my eyebrows off. Calls my makeup crayola and crazy art. She takes my drink, tries to drink it, then offer MY drink to her friend. She slaps people’s thighs and laughs. One day I had a hoodie on, and she put my hood on and tightens the drawstrings. We all asked her why, and she said “because I can” When I yell at her she thinks I’m playing. When I tell her I’m worried for her she’s says, “you should be”. She likes to burp in people’s faces and fart. She tried to throw my shoe across the gym floor. Right now she’s going to therapy, but obviously it’s not doing anything.
