DD is fifteen and a half. She has asked if she can go to a local village festival where there will be live music + other entertainment + beer tents etc. She wants to go with a few friends, then stay on for a sleepover at a friend's house which lives in that village.
My gut feeling is she's just too young to be left totally unsupervised all afternoon and all evening, in a large crowd of 2-3 thousand with ready access to alcohol. But this is my first time making a decision like this so I might be being over careful?
