We approached one another- he on the west side of Leavenworth, I on the east. In my hat and sunglasses I'm not sure he recognized me. My plan was to ask his name as we passed each other in the crosswalk. Suddenly he turned right, down Leavenworth. Toward O'Farrell. In the direction of where I live. I stopped, removed the crappy camera phone from my pocket and got off one shot.
As I came upon him at the corner, he suddenly skipped across the street, toward Union Square.
Foiled, I went on my way. Toward home, safe once more.
