I just finished my economics class and when I got back the heater is making this really loud, weird noise. I told our proctor and she said she'd try to have someone come look at it today, but didn't sound to hopeful. Stupid heater! The residences are heated by hot water, I guess it runs somewhere and heats the res, so that's what it sounds like, boiling water. I really hope that she can get someone to look at it today, that's going to make sleeping really hard.
