There is a curious social rule in the gym changing room, which dictates that a woman may preen and stretch and rub body lotion everywhere and prance about naked all over the place, but most especially in your way and in front of your locker, but you must not look at her. You must pretend she is completely invisible, even if she is standing right in front of you and has a tattoo of a target on her arse.

Do not look. She doesn’t exist. Look away, or she will turn you into stone, or something.
