Reply #5: I've tried to let him know in a polite way.

I can't really make enemies with the guy, because we're in the same department at the same university, so we see each other all of the time. He's another American who just moved here this year, so I helped him get this place to live and showed him around and things - generally trying to be a nice guy, especially since he and I have mutual friends from the US.

I think he's just a total fucking weirdo, and completely socially inept, which is saying something coming from me. For instance, I've gone down there to give him mail (all of the mail to the house goes through my door - fucked up, I know, but that's why the house is cheap), and mentioned that his apartment is incredibly warm, while mine is freezing, and that he controls the heat for the entire house. Has it not occurred to him that he could turn his radiator down so that the house warms up evenly? Probably not, and I guess I just have to tell him that.... seems quite awkward though. Right now it's fine, because I'm all for conserving energy and can put on extra clothes, but by December or January it will be too cold to live in here if he doesn't sort this shit out.
