The rules were if you forgot your trainers you had to do it barefoot unless it was outdoor PE, when you'd have to sit it out. Although there was the strict PE teacher who caught onto the fact that the same girl "forgot" her trainers nearly every time we had outdoor PE and decided to call her bluff. Told her that if she was going to keep forgetting them then she'd just have to get used to doing the lesson in bare feet.
She actually made her go outside with no shoes and socks on. Poor girl was horrified. And then she said "I'm not going to make you take part. But you are going to sit out here in your PE kit and no trainers and watch everyone else do the lesson in the hope that next week it helps you remember your trainers."
It was a strict lesson but she never forgot them again 😂
