The clincher was when they were going over some material about classroom / playground behaviour and bad feelings. They colour coded the feelings, like Blue is Sad and Red is Angry. Yellow was Wiggly, which described most fidgeting behaviours.

Teachers were telling kids that if you had any of the bad feelings you had to quietly sit by yourself until you're feeling better.

My friend has ADHD and took exception to the idea that being fidgety was a 'bad' feeling. And in general, none of these are ultimately bad feelings to have. I mean, nobody really wants to be sad or angry, but telling children they're bad for having feelings is fucked up no matter how you slice it.

I admit that if a child is disruptively angry, then a timeout is warranted. We have the same rule for adults, and if you can't control your temper then you need to cool off before you can be civil again. But telling kids that they can't hang out with their friends if they're feeling sad or fidgety is just cruel and pointless. It has potential to cause a lot of harm to a child's development for the sake of 'classroom discipline'
