qa, my question was not about when to teach kids chinuch. My question was whether chatting with police officers and delivery men when all the neighborhood kids are, is considered for girls a breach of tznius. The truth is that it is not tzniusdig for girls (and not the right thing for boys either) to shmuess with strange men.
I guess I’ll ask the right question now. How do I get my children to do the right thing which is the opposite what the other kids are doing? How can I get them to stay out of these conversations?
