Is this common? They are just friends and the boy is v interested in a different girl; dd is not interested in the boy, except as a friend. He has, apparently, often had sleepovers with girls in their group , sharing a room. Dd says her reputation will never recover if we make him sleep on the sofa.
I do believe that she has no interest in him, but dh says "he's a 14 yo boy! I know what they're like."
