Yeah, I remember one of my teachers (I think my high school biology teacher) chastising us a bit one day because most of the class would come from PE before hers. She was complaining that we smelled like sweat and working out and all that.
But we weren’t allowed (or given even close to enough time at the end of the PE class) to use the showers. You basically showed up, had until the second bell (about 5 minutes after the first) to be in the gym ready to go, you’d run/play/workout/whatever for almost an hour straight, and then be given at most 5 minutes to change and go to your next class.
No shit we stank, and when we asked why we couldn’t use the showers, we were told there was no way for us to be monitored in there, so it left too many opportunities for misdeeds and shit.
