I agree. A boy of sexual age and curiosity should not be allowed to sleep in the same bed as a younger girl or any girl or that matter. I wouldn't even allow them to sleep in the same room. I don't consider it being over protective. I consider it being protective in a society where CSA occurs all the time with hardly any repercussions for the abusers.

Personally I would've probably slapped that man who have lip about his son having no I'll intentions. He would've earned a punch of the comment of me being perverse. I would probably also report the man to child services. If anything were to hve happened he would've probably said boys will be boys.
