Forget about showering with my fellow students in Tribeca Alternative’s prison-style showers—one nozzle for four to six girls at a time—in the locker room. It was impossible to work up a sweat during what passed for physical education class at TAHS, so there was no need to shower, anyway.Well, impossible for me, considering that, in the past, whenever a volleyball or whatever came near me,I’d always make sure to step calmly away to avoid it. See? No sweat. No need for a shower. Problem solved.
