G.T.
There are always the "fighters" for some reason. I made it through school without ever getting in a fight and I'm sure the majority does. Teaching your children that physically fighting shouldnt have to be necessary is the best thing, but also teaching them how to defend themselves just in case is important too. My mom used to play fight with me. She always told me never to hit anyone first but if someone hit me and I couldnt talk my way out of it then I better know how to fight back. Luckily, I never had to show off my skills :)
I would also assume there is more fighting these days. The kids grow up with a lot more violence in their lives just as ENTERTAINMENT then we ever did.... so they don't know any better and think being physically agressive is the norm. Scary. I doubt it matters what school you are kids attend, kids are the same no matte what district they are in.
