Good friend took ds (8) for a long walk today while I was working. There were 3 boys (two 9-year-olds and my 8-yr-old). On their way back, she dropped them off at a playing field (which is not overlooked by any houses - it's on the edge of the village so they were totally alone) and drove home for an hour. I had no idea she was going to do this and the first I heard of it was when ds came home and told me. I know everyone has different ideas about when their children are old enough to be left, but I'd always thought it would be something I decided and planned for, not something that someone else would do to my child. I'm shocked, but have already decided not to make a fuss about it - will vote with my feet instead. What does anyone think?
