My sympathies.
Back when my kid was in public school, one of my kid’s classmates was removed from 7th grade Field Day for MIP and being under the influence. Vaping in class was common. Shudder to think what goes on at the high school.
My kid raised the idea of going to private school after comparing notes at sleep away camp - and realizing how far behind she was compared to her peers even though she was a top student at home.
Just an FYI: there can be drugs and drinking going on at boarding schools as well.
