“I understand,� I said. “It’s not the box’s fault that it disappeared. But what can we do? It’s disturbing to see things that have disappeared, like tossing something hard and thorny into a peaceful pond. It sets up ripples, stirs up a whirlpool below, throws up mud from the bottom. So we have no choice, really, but to burn them or bury them or send them floating down the river, anything to push them as far away as possible.�
