OK - I'll share a southern secret (this from someone born south of the Manson/Nixon - rasied north, then moved back south as fast as I could)
True southernerns are way to polite to ever say something bad about someone. Now this presents a problem, because often that's exactly what they are thinking.
So sotherners came up with the phrase "Bless his/her Heart".
Now this is how it works, first you say something that on the surface seems like it could be positive - for example - he tries really hard.
Next, you add "Bless his Heart" - so it ends up - He tries really hard, bless his heart. Which sounds OK on the surface
Now, having lived in both the north and the south, I can translate this into yankee. A yankee, who wouldn't hesitate to say something bad about someone, would say -
He couldn't do it if his life depended on it. He's a ****ing idiot.
Now, that's what the southerer was thinking - but doesn't "bless his heart" sound much more polite.
Now you know - and I apologize to all southerners that are mad at me for providing this translation.
