:iagree: At a time when I've been frazzled with children (and I only have two), I "politely" interrupted them and said "I'm sorry, I'm really busy right now." But yes, if an adult comes to the door, all the salespeople or church people that I've seen will continue with their spiel, no matter how frazzled the adult looks. We've stopped answering the door. I don't care if they know we are home or not. Actually, I'm contemplating putting a sign by the door bell.
