A friend of mine is in a house sharing situation with six roomates. Three, a woman, her boyfriend and their 5 year old daughter, live in a downstairs self-contained apartment. My friend lives upstairs, and has a young woman with a 6-year old daughter, as well as another guy in his late 20s. Each person has their room and share the kitchen and the bathroom. There is one extra room which is a common room and does not belong to anyone. The problem is the second guy. Basically, he won't let a fly fart in the house without his express written permission, but he somehow feels entitled to piss on everyone else who lives with him. He expects everyone to do the same amount of cleaning although he makes a bigger mess of things than anybody else. He's actually labeled the shelves in the pantry and in the fridge and even the sponges on the sink. One time, he let himself into the downstairs apartment and into their bedroom without knocking to complain about something or other. Also another time when he thought my friend wasn't home he also let himself in to do who knows what. My friend being there stopped the guy in his tracks and me friend has since put a lock on his door. He has engaged in shouting matches with the woman downstairs (when her boyfriend wasn't there) in front of her daughter. The incident was the usage of the common room. It is a smallish room that leads to his room. He put up a curtain so he could close it whenever his friends came over. My friend took it down because the guy is not paying for that room and he doesn't want the other guy to start feeling entitled to it. Needless to say no one else who lives in the house (or the landlady) can stand the guy and wouldn't mind seeing him gone. What options do they have to get either get the guy in line or out for good? Humorous, evil responses are also encouraged. Gotta have some fun.
