The best place for discovering what a man is is the heart of the desert. Your plane has broken down, and you walk for hours, heading for the little fort at Nutchott. You wait for the mirages of thirst to gape before you. But you arrive and you find an old sergeant who has been isolated for months among the dunes, and he is so happy to be found that he weeps. And you weep, too. In the arching immensity of the night, each tells the story of his life, each offers the other the burden of memories in which the human bond is discovered. Here two men can meet, and they bestow gifts upon each other with the dignity of ambassadors.
