Bullying is terrible. My son was bullied and the bully had more rights than the victim! It was awful. I had to go all the way with it, file the Dignity for All Students reporting paperwork and report to NY state, and finally it was dealt with. The whole "zero tolerance for bullying" campaign that is in many high schools is complete crap and means nothing.I completely understand the mindset of what was said above in regards to bullying but that is not the answer. As a matter of fact most kids who are bullied are not capable of physical confrontation or that would have been handled immediately.
There was recently was an 8th grade girl near my area who committed suicide due to bullying. It is still a huge problem. There can never be an option to just ignore it because you think the coach/administration will do nothing or it will make the situation worse. You know what makes the situation worse, a kid who thinks the only way out is suicide. That's what can happen when nothing is done.
You report it and you make them listen and do something about it. Even with all the anti-bullying campaigns that have went on it boggles my mind that school administrators, teachers, coaches, and most importantly the parents would just brush it off or ignore it (and it certainly happens). Be happy that your daughter actually told you about and didn't hide it.
Sorry, this just bothers me. Bullies suck and should not be tolerated or excused in any way. Speak up and make someone listen.
