DD is 17, she wants to go to a festival 80 miles away. She's so irresponsible and I know she'd be , though she reassures me that she won't lose her virginity and have sex with 3 ramdomers like someone she knows did last year. I just don't think she's sensible enough yet and she is now sulking I've asked to compromise and go for the day rather that stay in a tent, I know she'll be 1 next year and will go then anyway meantime AIBU?
