In the short period that I worked with kids, one thing that worked remarkably well was just to... like... talk to them like they're adults. Nobody ever fucking does that. And none of them like being talked down to. Don't downplay the fuck ups they've done, but explain clearly why it was wrong and try to CONVINCE THEM your point of view makes more sense. Don't start telling them "no you're wrong" off the bat. If the kids hadn't told me they liked the way I treated them, I never would've known that's not the norm. It's mind boggling to me people just repeat the way they were treated as kids onto the new kids. I thought we learned this lesson in the 90s already? Or maybe in the 80s? 70s?
