"Fix it up," Tom grated. He was beginning to see the whole picture; his self-control was about to snap. "I'm not getting a new one! I want this one fixed!"

"Sure," the serviceman said, resigned. He began making out a work-order sheet. "We'll do our best. But don't expect miracles."

While Tom Fields was jerkily signing his name to the sheet, two more damaged Nannies were brought into the repair building.

"When can I get it back?" he demanded.

"It'll take a couple of days," the mechanic said, nodding toward the rows of semi-repaired Nannies behind him. "As you can see," he added leisurely, "we're pretty well full-up."

"I'll wait," Tom said tautly. "Even if it takes a month."

"Let's go to the park!" Jean cried.

So they went to the park.

It was a lovely day, with the sun shining down hotly and the grass and flowers blowing in the wind. The two children strolled along the gravel path, breathing the warm-scented air, taking deep breaths and holding the presence of roses and hydrangeas and orange blossoms inside them as long as possible. They passed through a swaying grove of dark, rich cedars. The ground was soft with mold underfoot, the velvet, moist fur of a living world beneath their feet. Beyond the cedars, where the sun returned and the blue sky flashed back into being, a great green lawn stretched out.

Behind them Nanny came, trudging slowly, her treads clicking noisily. The dragging grapple had been repaired, and a new optic unit had been installed in place of the damaged one. But the smooth coordination of the old days was lacking; and the clean-cut lines of her hull had not been restored. Occasionally she halted, and the two children halted, too, waiting impatiently for her to catch up with them.
