My 11 year old daughter is constantly being invited on trips into the local town by a couple of her friends (same age), with no adult supervision. I am very uncomfortable with this, especially as I don't know all the girls involved, and have said no. I personally don't believe they have the maturity to cope should anything untoward happen, or, as girls are prone to do, I can imagine them falling out and my daughter ending up stranded alone in the middle of nowhere! Am I being over protective?
