Where: New York City
It was towards end of the day and the metal of this pre-war building started to glow.
I waited for the right person, wearing the right clothes, with the right gesture to come out through the revolving door. But nothing. That door seemed like it was on lock down, but soon the perfect person walked by in front of the door vs coming through it. To my delight he stopped and waited for a bus.
When I saw the letter P on his hat was a similar hue as the glowing metal, I moved my position just a bit so that the P was in the the middle of a dark rectangle within the revolving door.
