I can relate somewhat. When I see my roommate just throw clothes into a pile on the floor, I'm compelled to pick them up and put them away. When he puts stuff in the middle of the floor, I move it so I can walk. I don't think he's used to it. One time I dusted the entire room and put all loose papers into a folder for him, but I somehow threw out a credit card number or something, so he told me to stay away from his desk area.
