I read texts from DD's (16) BF (15). He said he was camping in a public field with friends but his mum thought he was at a mates for a sleepover. He was texting to persuade her to go and join them. She told me he was at a mates for a party as she wouldn't say where and looked a bit shifty I said no.
My dilemma is that his mum is a very close friend. I feel bad withholding his deceit from her yet have been deceitful or at least sneaky myself.
What would you do?
