There is a sound you sometimes hear after midnight, high up in Manhattan. It comes from maybe thirty blocks away. Very faint. In the stillness of your mind, you know it is a lonely taxi horn dancing with the doppler effect. But in the small hours of the city, you wonder who might be riding home amongst sleeping millions, and how boozily, and what love affairs or personal dramas are about to begin or end. New York is like that. In its darkness, taxis are crickets, and you listen.
