sharing

im an only child which means i have NEVER had to share a room with some one. so this comming to college and having a room mate really scared me. this room mate i got sucks she touches my stuff with out asking. she leaves her dirty clothes every where and she just annoyes the hell out of me. I work at night and when i come in she has music blasting all the lights on and food every where so it starts to smell bad... i cant stand it im tryingn not to go off on her but i got the feeling its comming....
