Damn BF, i agree with you. I would have been a f**k up no matter where i was schooled.
One thing i can attest is that behavior boarding school is a lot worse than both. I left in year 4, i was top of the year in school, just dominated everything, then i got bored and mucked up when i had nothing to do, and nothing that challenged me. Which was often. Got sent to boarding school for a year, and that taught me the way to get ahead is to beat the shit out of the loudest mouth at the school, and the crazier you were the more the other students respected you. It was more than a bit f**ked up.
Of course the lessons learned at that shit hole carried on through the rest of primary and most of high school. Even still i have to fight not to stand over merkins.
Don't send your kids to boarding school folks.
