I noticed that some folks are afraid to make eye contact with me. I've been noticing it a bit more lately. Especially blacks. I remember this was the case long ago, and now it seems to be back. Or it could be I'm just noticing it more. So I tried going out of my way to say "Sup" to blacks that are looking at the ground rather than look me in the eye. Almost every time they respond in kind. Try it and see how it works. I don't care if he or she is dressed to the nines or wearing a hoodie and saggy pants.
