I want to take my jacket off

Because I don't want to get FOOD on it. But it so gosh darn cold in the hallways, and in the cafeteria for that matter. It is so interesting that they don't heat the hallways here. Every time you walk out of any room it is like you're walking outside, but you're NOT. It is really frustrating, having to dress up to go to the bathroom, or wearing your nice big jacket to lunch. I know that one of these days I'm going to spill something on it, and I am going to lose it.
