I get along with black folks better than I do with white people... There is an energy that folks give off toward each other that is unmistakable... If its love (or even like) it gets picked up... If its hate, it gets picked up...
Kinda like Son House saying "Don't mind people grinning in your face"... What he is talking about is mostly Southern behavior where people are giving off the hate vibe but with a big ol' grin on their face as if they like you... Son was a smart man and a preacher... His point is that even folks that might hate you might be grinnin' in your face but that beat the heck out of stringin' you up from some tree...
