she was obsessed with you. She knew literally EVERYTHING about you.

You guys were in your dorm room and she barged in the room. Well yea, you were roommates..but she could of at least knocked before she walked In like that. But you didn't give her hell for it since it was only your first week of collage

As she walks in. She looks at you with this.. creepy smile and looks you dead in the eyes and says

"You must be my roommate. Nice to meet you!"

She knew very well she knew you
