I lived in the dorms last year, but I'm going to live in a house with a few others this year.
I had a roommate; she was really nice. When I told her I had trouble speaking sometimes, she offered to chip in for a whiteboard so I could write things instead.
Unfortunately, writing doesn't always help my person-to-person communication problems.
It was also a little awkward because I'm not a girl and she was, but that's a different issue entirely.. Mostly, I liked having a roommate, but I don't think I could have dealt as well with many other people for roommates. We had some similar interests, and she didn't mind when I went on about maths and stuff.
