When I was six or seven years old, growing up in Pittsburgh, I used to take a precious penny of my own and hide it for someone else to find. I was greatly excited at the thought of the first lucky passerby who would receive a gift in this way, regardless of merit, a free gift from the universe. . . . I've been thinking about seeing. There are lots of things to see, unwrapped gifts and free surprises. The world is fairly studded and strewn with pennies cast broadside from a generous hand.
