Progress update

At the office in New York. Where a few months ago there were workmen and the world's most awe-inspiring crane throwing up the bare bones of a building, today stands a glass-sheithed 35-odd storied skyscraper. There is glass up to the 30th floor, and on the 16th, eye level to me, a guy is sweeping up. Is this a normal progression? Will he sweep his way along behind the upward progress of the building, or did he just spill his french fries? It's pretty late for a construction worker to have been eating lunch.

Meanwhile, along the building's exterior, construction elevators and their counterweights alternate with mesmerizing regularity, as if there were some swank club up there.
