Discipline

Anyone who grew up in the 50s 60s or 70s...that disciplinary ship has sailed. I’m not advocating hanging kids by their thumbs but the tolerated bad behavior is a symptom of bad parenting plain and simple. Yes there’s the occasional sociopath kid but generally asshole parents produce asshole kids and the circle remains unbroken....
Boom...there I said it!

I dont have kids, nor do I pretend to know what is best. But, in my ignorance, I think I would make him/her responsible for a daily, classroom task.
Something I could give praise for.
Channel that energy.

How I deal with anyine, put them in their place and explain why they are being rude or stupid, or whatever the case is

I’d send him to the principal office
