When my sister and I both sat at the dinner table we were instructed, "Don't talk to strangers," AND "Don't take candy from strangers."
The following day my sister saw a friend taking candy from a stranger and became alarmed. She told her friend, "Don't take candy from strangers."
So now comes elijah23 and he heard both commandment given at the table, because he was a guest in our house. He went to my dad and said, "Your daughter didn't teach what you wanted."
He also asked, "Why did you name her Paul?"
When I spoke to my dad about it later he said, "Invite your friend to supper more often. He is a son to me."
