It hasn't quite been two weeks, but already I can feel the stress lifting. Yep, the roommate from hell is gone! After one final act of selfishness -- 'borrowing' (without asking, of course) my air mattress and leaving his cheap-ass one with me (and trying to explain, via email, that really, they were the same, trust him, and if I wanted mine back I could pick it up at his new residence), he finally packed up and left. For two weeks after my ultimatum he 'lived' in my house -- coming and going at odd hours, using the internet until I removed the modem from the house -- and each day I found more of his stuff and left it in his room so he wouldn't forget it. He promised -via email - that he would hire a cleaning person to clean the bathroom and his bedroom before he left. This hasn't happened, and anyway, I've cleaned his bedroom, knowing that he was just too lazy to get anything done. A guy who passes the bar yet doesn't bother to register with the state a year after he qualifies is slovenly, not merely lazy.
All the neighbors are thrilled that he is gone. They toasted his departure and doors around the building have been locked ever since.
