Dias,
When I was in school I got into a disagreement with a girl...I too didn't fight back... I wasn't to smart though because I was afraid of my dad and thought he would get upset with me if I was in a fight in school...I allowed her to hit me many times... ending up with a black eye... and later a knocked out front tooth...that is when I finally got mad enough to protect myself. I hit her once and knocked her out and I just waked away. I didn't get into any trouble with the school because I wasn't one of the kids that was always in the office for getting into fights...
I have always told my kids... don't start the fight but make sure you finish it... one of the things that happened with my nephew a kid tried to bully him and he just went up to the kid and told him come on... tell me when and where...kid got so scared he just backed off and never has been bothered again by the kid,
