The blessing and curse of being a Mainer is that when people think Maine, they think lobsters and blueberries. They don't realize that we have honed our stealth attacks through decades of having to be polite to tourists so they will continue to give us their money.

A Southerner would have just said, "Oh, bless your heart!", safe in the knowledge that you don't know that you were more or less just told to go fuck yourself. Stealth manners can be employed in many different ways. :D
