 In a gray city, two glass and metal towers rise symmetrically, joined by a glass-covered walkway. A middle-aged man, dressed like everyone else in suit, white shirt, and tie, sits at his computer screen. He notices another man who looks like him and who works in the other building. It upsets him. He follows his twin into the subway station at day s end. They are on opposite sides of the tracks. Whatever our man does, his doppelganger imitates. A train pulls in, but our man does not get on. He waits, hoping to catch out the other. A hobo watches each imitate the other, until our man thinks of something the other won t do. Is this a freeing triumph of the imagination?
