" Don’t go anywhere, don’t do anything, don’t call anyone. I guessed talking with the guy would amount to doing something, which would contravene the don’t do anything part of the command. But then, breathing was doing something, technically. So was metabolizing. My hair was growing, my beard was growing, all twenty of my nails were growing, I was losing weight. It was impossible not to do anything. So I decided that component of the order was purely rhetorical. "
