I am very uncomfortable with this but am I over-reacting? DD1 who is 8 has just come back from her friend's house, she was there a couple of hours. During this time friends Dad (who is looking after them) left them in the house twice, to first drop someone off and second time to nip to the shop. Girls were left in house, elder brother 13 or 14 was upstairs with 3 of his mates, none of whom I know anything about. I never leave dd anywhere on her own but even if I did I wouldn't if I was responsible for someone elses child as well. So does anyone think this is OK? Not sure what to do about it tbh.
