Ya idk why you're getting down voted. I grew up here and went to public school. It didn't matter what quadrant you were in, kids just go wild once they hit Jr high. Someone else said it, it's the time where you learn a lot of rules were fake and start pushing boundaries, plus for city kids it's around the time where you gain a lot of independence even though your brain is still figuring out what are good ideas and what are bad ideas. Freedom + no risk aversion + thinking you know best = messy adolescence doing crazy stuff
