haha my housemates are such dorks. We removed most of the interior doors for the sake of circulation, since theres freaking dozens of them. I come home today and they are all back on. I ask why "To lower the heating costs". Why the hell NOW of all times? They also said they turned off the furnace and are using space heaters now. OH JEEZ GREAT GUYS! Now I have to convince them they are wrong, and its going to require printing some sh*t out....
