The lesson of that kind of reading is a simple one. It has taught me that my own life is ephemeral. Despite all the heroic myths about the unique, irreplaceable preciousness of our daily lives, I am absolutely convinced that someone, someday 50 or 100 years from now, will be working at a computer near where I am seated right now, and he or she will come across the address of my office mentioned in this article—902 Broadway—and will read with amusement or wonder or puzzlement about my experiences. I greet you, and the people who follow you, and the ones after them, and I hope that I give you a moment’s satisfaction, and that you take as much pleasure from your search as I did.
