New York was an inexhaustible space, a labyrinth of endless steps, and no matter how far he walked, no matter how well he came to know its neighbourhoods and streets, it always left him with the feeling of being lost. Lost, not only in the city, but within himself as well. Each time we took a walk, he felt as though he were leaving himself behind, and by giving himself up to the movement of the streets, the world was outside of him, around him, before him, and the speed with which it kept changing made it impossible for him to dwell on any one thing for very long. Motion was the essence.
