I've become a collector of stories about unlikely returns: the sudden reappearance of the long-lost son, the father found, the lovers reunited after forty years. Once in awhile, a letter does fall behind a post office desk and lie there for years before it's finally discovered and delivered to the rightful address. The seemingly brain-dead sometimes wake up and start talking. I'm always on the lookout for proof that what is done can sometimes be undone.
