Roommates

Last night, before I went to bed I set the thermostat to 70 degrees. Around 5:30 in the morning I woke up freezing, my nose was running, and I had a sore throat. So I hopped off the top bunk and went to check the thermostat, and come to find out my roommate had lowered the temperature to 60 degrees because he was hot, and is an idiot. Now I can understand that he was hot, but he could have just slept with out the covers or something, but instead he decides to turn it down to 60 and make me freeze, because I have top bunk for obvious reason if you know my roommate, and the top bunk is right below the air vent, so lets just say he really ticked me off!
