..."Mom Solution" versus "Dad Solution", which will happen REGARDLESS of divorce or not.
My wife and I went through this. Boys come home, tell me that they are being picked on. Mom says tell a teacher, I say, "Wait for him to take a swing, knock the SH!T of of him..." Mom got upset that I suggested that, I got upset that she wanted him to tell, knowing that boys are GOING to fight (it is merely recently that this, "Anyone fighting gets suspended" rules have started), it is a guy thing, and it determines pecking order. Pack mentality, if you will.
So, here is how we solved it. If he tells a teacher, and the teacher does nothing, MOM goes to school to handle it. If he gets into a fight, and gets suspended, DAD(me) goes to the schools and handles it.
Personally, I have told my son that if HE starts a fight, he should be prepared for an a$$ whipping when he gets home, but I will NOT tell him to stand there and let someone beat the crap out of him, so he doesn't get in trouble. If he gets suspended for defending himself, I will back him all the way, and he will NOT get in trouble. Of course, this is Texas, where, on an episode of COPS, they rolled up on a bar fight, all the witnesses said guy A started it. Guy A was lying on the ground, bleeding like a stuck pig. Cop walked up, said, "Wow, you picked the wrong guy to mess with, huh?" And cuffed him and hauled him away for assault.
And, honestly, the way the schools have become all touchy feely lately, you might consider that if your son IS attacked by some kid, he might not be ABLE to get away to tell a teacher. And if the attacking student pins him down and begins pummeling him, and a teacher DOES see it, BOTH kids are probably going to be suspended or punished for fighting. Might as well teach him to defend himself, but tht is just MY opinion, and of course, I would defend my opinion.
Why give a "senior" discount, they have had plenty of time to raise the money...
