Went out shopping today with most of the family and left my 14 year old dd waiting for her 14 year old boyfriend to arrive. I didn't think anything of it as I trust her and she often stays on her own or has friends round. But on the way home I suddenly wondered whether I am asking for trouble or whether her boyfriends mum would mind them being on their own.I have a good relationship with my dd but when is it not ok to leave them on their own age 14/15 or 16 or never!!!
