12 is the magic number when things start going to shit. I'm sorry for what happened to you but maybe you should start a counselling service for clueless parents and tell them what should they do and what they shouldn't to correctly shelter the children. Because sheltering is an art. I think about it all the time. I always wish some one would take a bit of money but tell me how to guide or not guide my child to be independent in the rough world and to take decisions independently

I watched an older sibling go off the rails. That is what kept me from doing it.
