One year in college I lived with 2 other guys, and it worked pretty well, until we all met some other guy and decided to let him move in, to help with the rent and utilities. He seemed great at first, willing to take the basement area, and hardly ever coming out of it really.
Then the first bills came in that he'd be partly responsible for.
He never paid his share of the gas bill, which, for the 2 months he lived with us, became QUITE expensive, as he demanded we keep the heat up (in our sparsely insulated slum-lord type apartment/house), since he was in the basement. I think his share was like $70.
But then we got the phone bill! To our surprise (since he "entertained" some girl down in the basement virtually every night) he evidently had another girlfriend that lived in Alaska, who he called every day, for HOURS. (we were in Ohio). A whopping $200+! And that was for just ONE month.
We kept asking him for money to pay it during the next month, and he promised us he'd "hit up his 'rents (parents)" for it, but we never saw it. Of course, being the trusting idiots we were, we let him go on for the next month, and then he racked up ANOTHER huge bill!
All told, he ended up owing us over $400 and never paid a dime of it. We came home one day to find most of his clothes gone, but some of his furniture in the basement. We tried to call his parents, as we tracked down their number somehow, I can't remember how. They gave us the runaround, and finally just said to us, "Just keep his furniture, it's worth a lot". Like we were some kind of consignment shop or something!
Soon after that, my other roommates had moved to another place, I went somewhere else...Long story short, I pretty much swore off roommates after that, and I'll NEVER have another one again, unless it's some sweedish bikini type...that I'm married to of course. :) (Hey a guy can dream!)
LOL. I'd still be trying to track that guy down, if I were you!
