“When President Warren gave them to you, he said the best guess for when they’d hatch might be ten days off either way.” Jonathan Yeager spoke with the usual impatience of youth for age. He’d turned twenty not too long before. Sam Yeager didn’t like thinking of it in those terms; it reminded him he’d turned fifty-six not too long before. Jonathan was already on his way up the hall. “Are you coming or not?” he demanded.

“If you don’t get out of the way, I’ll trample you,” Sam answered.

Jonathan laughed tolerantly. He was a couple of inches taller than his father, and wider through the shoulders. If he didn’t feel like being trampled, Sam would have had a devil of a time doing it. The overhead light gleamed off Jonathan’s shaved head and off the body paint adorning his chest and belly: by what it said, he was a landcruiser-engine mechanic. Young people all over the world imitated Lizard styles and thought their elders stodgy for clucking.

Sam’s wife Barbara was standing in front of the incubator. The new gadget made the service porch even more crowded than it had been when it held just that washing machine and drier and water heater. “One of the eggshells already has a little hole in it,” Barbara said excitedly.

“I want to see,” Sam said, though getting close to the incubator in that cramped little space wasn’t easy. He went on, “I grew up on a farm, remember. I ought to know something about how eggs work.”

“Something, maybe,” Barbara said with a distinct sniff, “but nobody-nobody on Earth, anyhow-has ever watched a Lizard egg hatch till now.”

As she often did, she left him struggling for a comeback. While he was struggling, Jonathan gave him something else to think about: “Dad, may I call Karen to come over and watch them with us?”

His girlfriend was as fascinated by the Race as he was. She wore body paint, too, often with nothing but a tiny halter top to preserve the decencies. She didn’t shave her head, though some girls did. But that wasn’t what made Yeager hesitate. He said, “You know I didn’t get these eggs to entertain you… or Karen.”
