I’ve heard he was in the Vietnam War and that fact by itself could explain his odd habits. He can be seen walking across parks, lots, even crossing the street in the same manner. Five paces and a three step turn. Once isn’t such a huge deal, but he’ll do it all the way down the block. He makes me dizzy watching him, I can’t understand how he stays in a straight line. I’d hate to see him walking a dog that way.
And at first, his dance almost seems comical and then a little tragic, until I consider that this type of behavior might have been cultivated in a battle zone. Being aware of everyone around him at all times likely kept him alive.
