““Nine o’clock came and I was allowed to go upstairs and take a shower. I had a half an hour before bed. I got undressed in the dorm with a towel around my waist. One of my roommates told me to put my underwear on top of my locker. “Why?” “So they can collect them.” “Who?” “The staff. So they can check for skid marks.” “What?” “Skid marks.” “I’ve never heard of that.” “Shit stains, man. Shit marks on your underwear,” he said laughing amusedly.””
