Coincidence is a recognized element in “real life.” All of us have anecdotes about those times when, by the merest coincidence, we avoided some disaster or stumbled onto some wonderful experience.
My personal favorite series of coincidences involve the narrow margin by which I nearly did not meet Roger Zelazny, a person who would become very important in my life. At this time, Roger and I had only exchanged a handful of quite formal, if cordial, notes. I thought that would be it.
Then Coincidence One hit. A friend mentioned to me that, although his office didn’t usually receive such materials, a flyer for a science fiction convention had come in his mail. He went on, “The writer who has been kind enough to answer a couple of your letters is the guest of honor.”
I’d never been to an SF convention. Neither had any of my friends. We decided to check this one out. I wrote Mr. Zelazny and asked if he would mind if I introduced myself. (This was back in the days of snail mail).
Many days passed, and I received no reply. I concluded that I had overstepped the bounds of propriety. My friends and I would still go to the convention. I would attend talks and readings, but I would not put myself forward.
