Bears repeating!
Thank you. Given the regular bad outcomes at school social events, it’s rather surprising that schools are still holding dances at all. Proms aren’t even a big community interface, as sports events are ... more a nuisance at worst, a minor amusement (a crowd of prom-dressed teens at PetsMart?) at best.
And they can mandate no “freak dancing”, dress codes, etc if they want to.
