He looks out the window at the falling snow, then turns and takes his wife in his arms, feeling grateful to be here even as he wonders what he is going to do with his life in strictly practical terms. For years he had trained himself to do one thing, and he did it well, but he doesn't know whether he wants to keep doing it for the rest of his life, for that matter, whether anyone will let him.
