DD had a party yesterday as their band conductor was leaving. It's a village/small town band so all ages. Parents were not invited. It started at 8pm and we said that she needed to be home at latest 10pm, and she should send me a message and I would come to meet her.
At 10:10 I walked down to get her as I hadn't heard anything. When I got there there were three kids her age and younger messing about on the roof of the porch. One had climbed out the first floor window and was standing on the sloping roof posing, one of the others taking photos. Seemingly no adult in sight, they were all in the function room on the next floor up.
She was most aggrieved she was the first to leave and there were younger kids allowed to stay later.
How late would you let your 12 year old stay out at something like this?
