Coincidentally (or not) my son, Tyler, had an altercation with 2 high school kids from the neighborhood the same day. He was jumped and hit several times. He was outnumbered and walked away with some bumps and cuts. When he got home, my wife noticed something was wrong (I had already confronted him about being late, not noticing anything was wrong). He gradually, and grudgingly, told us what happened. He didn't want my involvement. He wanted to handle it himself with the guys individually. His 'street sense' of what needed to happen was: no adults, one-on-one revenge, maintain image in the neighborhood. I talked with him about how revenge was a dangerous cycle. How he needed to stay away from that part of the neighborhood. Then, even with the passage about turning the other cheek still fresh in my mind, I gave him the best instruction I know on how to subdue an opponent by striking or choking. Tyler asked, as he has before, about taking boxing lessons. I had told him in the past to do some research on it and get back with me, which never happened. This time I did the research. I found a place called Core Combat Sports that teaches boxing, martial arts and MMA. We're going to check out all the classes and see what we're interested in doing together.
And, the hardest part, how should we instruct our kids to handle themselves when confronted with violent bullies who want to harm them? I personally don't know any parent who would say: just turn the other cheek son. That doesn't mean fighting back is right either though.
