I would end any staying over trips. I would dress in my pink fluzzy slippers, try to find out where the girl was drinking and go there and mortify her just by my presence. And I would turn in taverns etc. that sold drinks to 14 year olds. I would also wear pink fuzzy slippers and rollers in my hair and sit next to my daughter in expensive private school and just watch her behavior change after that. We have one great power and that is to embarass kids...use it. mg
