Interesting thread rumtumtigger.
How brave of you to post flip. It's enlightening to hear the views of a parent and to learn that it's also tough for the parents of the violent child.
My dd went through a phase of not wanting to go to school because of a particular group of boys. It has got better, but I've seen those boys and they're contantly irritating the others. I sat through a yoga class of dds which one of them absolutely ruined for the other 29. My dd has stopped going to yoga because of this. She used to love it. One little shit spoiling it for 29 kids. How fair is that.
I get angry and find myself thinking how lovely it would be if these trouble makers could just be isloated from the group, Who gives a shit what their needs are - they're infringing the needs of all the others so surely, in the interests of democracy, they should be isolated until they, their parents or a counsellor can help sort out their behaviour. If this is not possible, they should be educated at home, away from the others.
I know this sounds extreme, and Flip it must make hard reading for you, but perhaps not surprising. It really isn't fair on anyone else. If I were the mum of a violent kid, I would take him out of groups and parties like a shot. There's no way I'd let his behaviour impact on an entire group of people.
However, I also suspect that there is always at least one naughty boy (because it does tend to be boys) in every large group. Perhaps if that boy were removed from the group, another would fill in the space.
