When I was in school in the olden days, all girls from grades 7-12 had to take gym. We wore those God awful ugly blue gym suits. Taking a shower for most of us was a terrifying experience because no one in my family or friends families ever appeared anywhere to anyone else unless fully dressed. I doubt seriously if my parents ever stripped down in front of each other.
Kids in our local public school don’t take the same kind of gym class as we had and I doubt if most of them even work up a sweat. According to my grandson, none of the girls take a shower during the school day although the guys do.
All girls need to refuse to undress/take public shower. They simply have to express that they “feel like and self-identify as a non-showering, fully dressed person” at that moment.
When I was in school in the Dark Ages, after gym we were supposed to shower. The water was always COLD! the Anglo kids would wrap a towel around themselves, dash under the shower head and get a little water on their head, the run out rubbing like they were all wet.
The Hispanic boys, jumped right into the cold water and lathered up with soap and got clean! They probably did not have hot water at home and were used to cold water.
OK, I tried to dodge the showers also.
