I guess the fact that got to me about what my roomate did is that I chose to live with this girl.
I have some other horror stories from random roomate assignments while living in the dorms. Roomate #1 MADE drugs. Apparently, morning glory seeds + paint thinner = hallucinogen. After I moved out of that, I got put with a girl who accused me of stealing her stuff, told me I typed too lound and distracted her, I was not allowed to bring a portable TV with headphones so as not to disturb her...and the best part was the RA backed her up because she lived in the room first! After that, I had a private room for 3 semesters
