Well Joe I haven't been in school for a while... And when I was in school and was caught fighting, you would go to the principals office and get your wrist slapped.... But I guess times have changed
If one of my friends is in a fight, I will jump in if he wants help or if the other guy does something unfair like get one of his friends in etc.. Because I know they would do the same for me.
And if its two total strangers, I will just walk away... its not my business.
I have yet to be involved in a fight. Those are things I avoid at all costs since I see no benefit to them. I would defend my freinds if the need ever arose, but that has also yet to happen.
