I've lived by myself, with a wife, with a roommate and with my parents, brother and sister at various points in my life. I liked the solitude that came with living alone but I tend to hibernate and not leave the house for months on end, not good. The roommate I had was a lot like me, we had no problems and got along. He was a bit more social than me so it forced me to go out and meet people which wasn't bad. And I can't take living with my parents anymore, even staying for a couple days makes me want to stab someone.
