I’ve read some Britons online claim they had to do PE in their underwear as a child because they forgot their PE kits. And yes some of the classes where this occurred were coed.
It’s not 100% clear to me how common this practice is/was or how old the children who have to strip are. (I hope this practice ends before children reach age 10 although I’m not sure if it does.) It’s also not clear to me if this practice still exists.
This could never happen in a million years here in America. Could some people in Britain tell me if this practice went on at their school? I honestly was stunned when I learned about this practice.
