Twenty years of joy and support and friendship, that's a success. Twenty years of anything with another person is a success. If a band stays together twenty years, it's a miracle. If a comedy duo stays together twenty years, they're a triumph. Is this night a failure because it will end in an hour? Is the sun a failure because it's going to end in a billion years? Why does a marriage not count? It isn't in us, it isn't in human beings, to be tied to one person forever.
