My first roommate freshman year was pretty awful. She had a lot of odd habits, like pacing around the room grunting loudly to herself. She also locked me out of our room on a regular basis and would leave used menstrual pads in the middle of the room. My second roommate and I got along, but we were never really good friends. Now, several years later, I have a roommate again. We were really good friends before we decided to live together, and things have only gone downhill. I still consider her a friend, but most of the time I end up resenting her presence. I'm assuming she feels the same about me. We've had a couple of tear-filled blow-outs (which I've never had with anyone else I've lived with), but there are definitely still some moments of mutual friendliness. We cook for each other, do our laundry together, and generally resemble an old married couple who stopped having sex decades ago.
