This so much. There are few things I despise more than having to clean up someone else's mess. Unless It's my job, then go fuck yourself and clean it yourself. Everything of mine is safely with me. The only problem though is that if he didn't clean up their shit the house would probably get infested with bugs and rodents. And they won't be content with just the fatties rooms, they'd go after his too. So in a way what they do affects everyone in the house. I hope to God they don't have any pets because if they're fat they probably won't care if their pet shits on the floor, especially in a shared house like that. I went to an acquantince's house once and stayed over for some hours. The dog took a shit in the living room, they yelled at the dog, and left the shit. It was still there when I left. I also noticed dried shit at other parts of the house. I wish I was kidding.
