And what she understood-what none of the ones who came to touch Simon’s forehead understood-was that the misery of war represented the world’s only truly universal language. Its native speakers occupied different ends of the world, and the prayers they recited were not the same and the empty superstitions to which they clung so dearly were not the same-and yet they were. War broke them the same way, made them scared and angry and vengeful the same way. In times of peace and good fortune they were nothing alike, but stripped of these things they were kin. The universal slogan of war, she’d learned, was simple: If it had been you, you’d have done no different.
