One thing I want to make clear is that you may have opinions one way or the other but until the day you have to implement your beliefs, the day your child gets their first party invite, the day your child tell you her peers at school get drunk every weekend and have random sex at the age of 13, the day you actually have to FACE it in reality - well ONLY then you can really understand how this feels.
I just feel the need to add to this that I raised my sister through her teens so while my sig doesn't reflect it I have been there. I know we're all cool but just wanted to point out that many people's life experiences can be more than we realise.

I'm glad you and your daughter have made a decision and all is well. It sounded full on to me. I was lucky with my sister that she wouldn't have even wanted to go- she was a damn easy teen really
