There he was. Oblivious to the world around him.  A pair of noise cancelling headphones perched comfortably around his head.  A little quiet singing?  Perhaps. 

Just to his left, a woman walked quietly oblivious to the world around her.  No headphones but a smartphone would suffice.  A very serious conversation clearly in full swing.

Behind her, the double suit.  Two men walking together to the same destination (not sure how I could really discern that fact but I am confident) but oblivious to each other.  Not oblivious, however, to their blackberry devices.  Two sets of thumbs were moving so quickly they were just a blur. Kind of looked like one thumb.

As I watched this scene, I worried about each of them crashing into each other or something even more dangerous.  Just another morning on Madison Avenue . . .
