I don't have kids that age Bath but I have to say....HELL NO! I'm with you.

I'd have a nervous breakdown if my 13 yo daughter was wandering around in the city for hours like that. It's too young to be doing that without supervision. No matter how much I trusted my child I don't trust other people iykwim.

Your DH needs to remember too that the world is not the same as it was when we were that age.

God I sound like my mother!
