subtle glows

A hot, humid day, too hot. The sun pulled hidden strings today. It hid again and again behind clouds. New York, a Sauna with 8Million users. I chased shadows on the façades of buildings in midtown around noon. The lunch eating office workers looked at me suspiciously as I stood motionless in front of a seemingly unimportant wall between 48th and 49th street, waiting for the shadows to emerge. They appeared out of nowhere, their glow increased and then they just disappeared. The Rockefeller Center guard smiled. He walked by and away. I guess I was not supposed to take pictures of New York buildings here and now. It was obvious. I was hunting shadows. Or was it ?
