"Gee, are you sure? You won't change your mind?"

The delighted but uncertain look on his son's face shook Sam. He said carefully, "I won't change my mind. I've decided that it's possible to have too much of a good thing. If grief is a good thing."

Suddenly, for no reason that they could detect, the dog barked at them and backed away, the fur rising in an angry ridge along his back.

"Couldn't we take him along anyway?" asked Mark. "I don't like to think of him all alone here, year after year."

"He'll be miserable here, but he'd be more miserable away from his heap of dirt and stones. Perhaps—" Mark didn't see as Sam pulled his gun, then let it slip back into place. "No. That's none of my business. Maybe he'll be fortunate and have an accident."

"What did you say, Pop?"

"Nothing much. Come along, Mark. We're heading for civilization."

An hour later, the ship rose into the air. Through the blasting of the rockets, Sam thought—imagined, he decided, was a better word—that he heard the long doleful whine of a creature whose mindless grief was doomed to last for all eternity.
