Mind Your Manners

Gosh darn, hoogie-boogie youngin' whipper snappers! So RUDE!!!! Tell me, what do you think are the most important manners children should be taught, (e.g., hygiene, behavior @ home, restaurant, play dates, w/ strangers, seniors...) Any stories you want to share or opinions on which cultures have the best/worst manners? Who's fault is it that the kids of today are so rude & self-centered; or have children always been this way? I'd love to hear your thoughts!
