There was a tale he had read once, long ago, as a small boy: the story of a traveler who had slipped down a cliff, with man-eating tigers above him and a lethal fall below him, who managed to stop his fall halfway down the side of the cliff, holding on for dear life. There was a clump of strawberries beside him, and certain death above him and below. What should he do? went the question. And the reply was, Eat the strawberries. The story had never made sense to him as a boy. It did now.
