Interesting topic no doubt.... The school environment and society in general is much different than it was when we were in school. I had several issues come up this week that had to deal with this topic.
First was I ran into my son's teacher he had last year in first grade. She related a story to me about my son on the playground. He came up to her and told that some kid was trying to fight him, but he was not going to because the other kid was just trying to get him in trouble. He also added that he was not going to fight the other kid because my son knew he could hurt him if he wanted to. I think there a couple of life lesson in that story. I think I may write a book called "Lessons I Learned From an Eight Year Old".
Second was my neighbor's middle school kid got into a fight because he was taking up for a kid getting bullied. He basically told the one bulling the other kid to pick on someone his own size and the fight was on. Both kids got the same punishment. Is that right/wrong? Guess that depends on your moral compass.
The third was in my HS pe class. I have one kid in there that is constantly aggravating, instigating, harassing, etc. the other kids in class. I have dealt with him in class. I have sent him to the principal to deal with, but he continues. It has gotten to the point where he is reaching the limit of some of those in class and it will lead to a physical confrontation.
So there are 3 different situations and all could be handled multiple ways. What is the best way? I am not sure.... I guess the best you can do is to raise you kids by words and example as how you would want them to handle their lives and hope they live their lives in a way that reflects your values. Not sure this answered the question on how to deal with team mates...... My answer would closely reflect the words of B25, but maybe I gave some real life examples of how not everything is black/white.
