If you’ve never been in one, no need to comment “never”. For me it was over a decade ago as a teenager at a state fair. Quick fight broke out between an annoying guy and myself. He was following my little group around tossing stink bombs at us. A little pushing turned into a little punching. We both ended up in cuffs but neither with actual charges. We were both banned for the following 2 years from that fair.
Had a similar thing happen in middle school. Got jumped twice with one of them being inside the hallway of the school and them breaking my glasses. I blacked out and hurt one of them by slamming his head to the wall to stop it so the school and his parents called the cops on me which treated it as assault. Since it was in the hallway there were witnesses that came to speak to them and one of the teachers brining back my broken glasses so that didn’t go far past my lack of care for the authority there until I left at end of the school year*. The year before that one of our teachers encouraged that I fight one of those dudes in class since she considered her room where “beef is squashed” but I had no beef with them (rough city but I wasn’t involved in the street/gang drama the mid 2000s had going on). That school shut down 2 years later and became a new brand.
