Roommates from hell

I've had them.

I've had a variety of roommates in my day, since I moved around quite a bit during my college years.

There was the 18 year old gay guy with ADHD who had a different boyfriend every week and liked to leave his used condoms in the bathroom sink. He also never cleaned, did dishes or showed any concern toward his two roommates. He once moved in his friend and had her stay on our living room couch. She was initially only supposed to stay a few days but it ended up being a couple of months, and most nights her boyfriend stayed with her there on our couch. I finally had enough and complained to the landlady, who booted them both out of there.

Then there was the incredibly surly Taiwanese girl who lacked a personality, who I rented a room in the basement from. The room must have been a garage once because it was cold and had that concrete feel to it. The room outside my room wasn't properly isolated or even finished, and there was always a mysterious bucket in the hall that seemed to contain a head. I only stayed there 1 month, then I couldn't take it anymore.

I'm not sure that I can count an ex-boyfriend as a roommate, but I should be able to since we more or less lived like roommates anyway. We shared a bedroom of course, but we had separate finances and so on. He wasn't a bad roommate, apart from his tendency to be grumpy and just an all around bore. His brother lived there too, which was okay, apart from his lack of hygiene. His B.O permeated the house. B.O is one of those things that never gets any easier to deal with. You just don't get used to it. And I think as far as B.O goes, one of the worst smells is unwashed thick hair, apart from rampant sweat odor and other smells emerging from the lower regions.
When really thick hair hasn't been washed for a while, a particularly nasty odor starts to emanate from it, a smell so foul that it almost takes your breath away, but not in a good way.
