Mama used to tell us a story about a cicada sitting high in a tree. It chirps and drinks in dew, oblivious to the praying mantis behind it. The mantis arches up its front leg to stab the cicada, but it doesn’t know an oriole perches behind it. The bird stretches out its neck to snap up the mantis for a midday meal, but its unaware of the boy who’s come into the garden with a net. Three creatures—the cicada, the mantis and the oriole—all coveted gains without being aware of the greater and inescapable danger that was coming.
