Ugh... I hate when roommates are like that.., I had this happen to me about 4 years ago and it ended a friendship. I tried to talk to her but she was the one that started the mess and unless I apologized (when I did NOTHING except not take her crap) she wasn't going to give in. So we moved out. Me into another apartment and her back home to her very unhappy parents.

Start a conversation...?

What could you have possibly done to warrant this? Also, try talking to her. It is a two way street.

Eat an entire block of cheese and just sit in her room.

If you did something, even if you not do something, you need to initiate a talk to stop her behaviour. Seriously, living with a child is rough. On the up side, if she carries on, music can help you study so put on headphones and study away

duct tape is beautiful O_O

Time for her to grow up and talk about the prohl

open a can of whoop-ass!

Library?

Text her. I heard texting has replaced face to face conversation these days...you know people say things via txt that they'd never say in person.
