Hey slow down there

My son is going to a middle school next year so the wife and I were talking to him about the things he might face. My wife ask, "Well what if someone ask you to drink beer". My son replies, well I will eat gross stuff that has ketchup on it but that is as far as it goes". So she ask him, "What about if someone ask you to smoke cigarettes". And he says, "Cigarettes will kill you". My wife being pleased with his answers allows me to jump in and ask him a few questions. So I ask him, "Son, what if some girl wants to kiss you". "I will let her of course", he replies. The wife is now considering boys only boarding schools for him.
