I crept up slowly to him and sat by him without speaking. He didn't look up at me, but now I saw that it wasn't sorrow that made him look down, but something in the grass at his feet which he watched intently: a black ant of the largest kind. It struggled through the bending grasses, its feelers waving unceasingly.
"Lost," Blink said. "Can't find his nest, lost the path. Nothing worse than that can happen to an ant. For an ant, being lost is a tragedy."
"What is that? Tragedy."
"Tragedy, it's an ancient word; it meant a description of a terrible thing that had happened to someone: something that, given circumstances and some fault in you, could happen to you, or to anybody. If this ant ever finds his nest again, and could tell about his experience and the suffering he felt, they'd have a tragedy. But he's unable, even if he does get back. In a way, no ant has ever before been in the tragedy of being lost; this one's the first, because ants have no way of telling about such things, and so being forewarned."
