Late in this quiet meal Ann looked around curiously at her companions, suddenly awed by the spectacle of human adaptability. Here they were eating their dinner, talking over the low boom from the north, in a perfect illusion of dining-room conviviality; it might have been anywhere anytime, and their tired faces bright with some collective success, or merely with the pleasure of eating together--while just outside their chamber the broken world roared, and rockfall could annihilate them at any instant. And it came to her that the pleasure and stability of dining rooms had always occurred against such a backdrop, against the catastrophic background of universal chaos; such moments of calm were things as fragile and transitory as soap bubbles, destined to burst almost as soon as they blew into existence. Groups of friends, rooms, streets, years, none of them would last. The illusion of stability was created by a concerted effort to ignore the chaos they were imbedded in. And so they ate, and talked, and enjoyed each other's company; this was the way it had been in the caves, on the savannah, in the tenements and the trenches and the cities huddling under bombardment.
