Hot knobs

Dear Middy: Did I ever tell you about the time I ran screaming and naked into a room? I had been trying to operate a snakish "showerhead" that was attached to the faucet of an ancient bathtub. Hot knobs caused me to drop the thing, and a coiling spray of scalding water followed me around the bathroom. Only option: to break through to the room where I knew both my parents were sitting. I was 15, and we were on a church retreat.
