Spouse of mine: What?! You turned off the bathroom heater!!!!?
Me: Yes. We were gone for 4 hours. It's only 40 outside. It's not like the toilet is going to freeze over.
Spouse: But it's COLD!
Me: FOUR HOURS.
Spouse: But it dries our towels and is all warm and such with it on.
Me: We were gone four hours. Use the bathroom quickly. Your behind will survive.
Me: Four house of heater use. Quick! GO!
Spouse stomps off to the bathroom, and turns the heater on (what I'm guessing is) full blast. And brings a magazine.
