My daughter hated P.E. swimming classes in High School.
She eventually (and happily) got out of it by having a scheduling conflict with school orchestra session.
So to get out of the course - the P.E. teacher made her write a research report about swimming.
My freshman year (over 50 years ago) we swam naked in swim class.
My brother, a sophomore, told me a story about a day that was deemed co-ed swimming day. Of course, everyone wore swimming trunks, except for one boy, who didn’t get the memo. He left the locker room and walked into the pool area naked as the day he was born. To make matters worse, he was blind as a bat without his glasses. It took a few long seconds of “THERE ARE GIRLS IN THE POOL” from the boys before he ran for cover.
He is a professor at Yale.
