Please tell me if I'm being PFB. A friend very kindly offered to look after DS(4) and DD(6) yesterday evening. We were chatting about what they had been doing, partly as they had grafittied the front of the house with chalk (not the issue) and she mentioned she had been in the house at the time. So, DCs were outside at the front of the house unsupervised for 5-10minutes maybe more. To give some context, front garden has no gate, we're on a busy road with lots of cars and pedestrian traffic and the garden is very small and open (more of a yard) - so road very close. Am I being precious to think they should have had an adult within sight? Friend looked at me like I was bonkers when I asked if she was out there with them. DCs are reasonably road and stranger aware, but DS in particular can still forget easily.
