What I think is absurd, at least around here, is that schools are allowed to require that students wear a specific uniform, but they're not allowed to require that students have a coat
Maybe it’s different elsewhere, but I was born into a relatively cold+wet climate and moved to San Diego in elementary school. I didn’t bring a coat because it made me hot, I was acclimated to colder weather, and I didn’t want to carry it around.
They refused to let me go outside for recess for weeks because I didn’t bring a coat and refused to wear one from the lost and found. Finally, one day, they sent me to the principal’s office and called my mom in for a chat to discuss my misbehaving.
My mom’s response was, “You called me in from work for THIS?! If he’s not cold, he’s not cold! He has warm clothing at home. He’s capable of deciding whether or not he would be more comfortable with a jacket on. Let him go outside and leave me alone”
