Heat

Or rather, lack of same. I'm working from home because I had to wait for the HVAC guy to come and tell me why my house won't get above 68 degrees when the heat's on. He just left, and (to nobody's surprise) one of the electrical heating elements is out. It's a special order, so he'll have to come back for an installation.

Fortunately, the weather's not supposed to be that cold, so I'll survive.
