But here in New York I was ignorant, insignificant, unimportant—one in millions whose destiny concerned no one. New York did not even know of my existence. Nor did it care.”

Is that we are a little early, that
Today has that special, lapidary
Todayness that the sunlight reproduces
Faithfully in casting twig-shadows on blithe
Sidewalks. No previous day would have been like this.”
