One night I tossed for an hour while dogfights raged overhead, streaking my patch of sky with fire. At last I heard Betsie stirring in the kitchen and ran down to join her. She was making tea. She brought it into the dining room where we had covered the windows with heavy black paper and set out the best cups. Somewhere in the night there was an explosion; the dishes in the cupboard rattled. For an hour we sipped our tea and talked, until the sound of planes died away and the sky was silent.
