Back in the day kids grew up with Hollywood cowboy ethics, meet in the street at high noon and settle things like men.
Now a long of folks grew up with professional wrestling ethics, sneak up behind someone and hit them with a chair, have a few of your buddies help beat them down.
Unless you went off campus, if you got into a fight at school, even in the hallway before class, the teachers always broke it up before too long. I got into a fight one time in the locker room before gym. Some kid put me in a choke hold from behind, he had his face right my shoulder and I jacked him with my fist with my arm opposite where his face was on my shoulder. That didn't even last long. As I got older, the worst stuff happened outside of school, usually on the weekends.
Kids get in fights sometimes. It's part of life and growing up. If you are carrying a weapon to a fist fight, you are just asking to ruin your life.
