Just thought of this today when I had to wake up to pee (old man, weak bladder).
I HATE going to the bathroom in the cold. I HATE waking up in a cold room, walking down a cold hallway, and peeing in a cold bathroom. By the time I get back to bed my blankets have leaked out their stored heat and I have to spend valuable minutes shivering until they warm up again.
Petty, childish rant over. Next?
