I rented a room in a house when I first came out, the guy advertised for roommates in the local gay bar rag. The guy who was renting a room there when I first moved in was a bit crazy - we shared a bathroom and he went nuts when I put the wrapper from the package of toilet paper in the garbage can in the bathroom, rather than bring it downstairs to the bigger kitchen garbage can (or the one in my room).
Second roommate was a young guy the landlord had the hots for. The guy went into my room his first night there, found some spare credit cards in a box on my dresser, and went on spending spree the next day. I was in the basement moving some of my stored stuff to make room for his while he was going through my room. He helped himself to a shirt from my closet to wear at the restaurant he waited tables at, the collar was nearly impossible to clean since he'd been carrying trays on his shoulder.
So...very glad to have my own place now. I've had roommates from time to time in the 20 years I've lived here, but always someone I knew ahead of time.
