Dear teachers and Students of reddit what school rule never made sense?

you werent allowed to throw snowballs because of the fear there could be stone or ice in it.

But it was perfectly okay for kids to play football on gravel where we often kicked up dirt and stone which flew into other people as we kicked the ball. and in winter the field often froze over and became a slippery ice field where everyone could play. injuries were common but rarely anythgin severe and everyone just got tougher for it, but dont you dare throw some of that newly fallen snow around
