MY FACE. IT'S FROZEN.
No but seriously it's so cold it hurts to breathe. They weren't kidding when they warned us to layer up for the night - teahouses typically have no heating. I'm in thermals, 2 layers of fleece, a down jacket, inside a thermal sleeping bag, underneath a comforter, and still I've woken up because of the cold. I burrow completely into my sleeping bag, leaving only the tip of my nose exposed so my roommate, Lynda, doesn't find a corpse next to her in the morning.
