"My analysis was correct. It wanted attention. The parents left so hurriedly, they forgot to give me permission. When I didn't come to investigate, the child stop—"

The wail burst forth with renewed vigor.

The robot rotated its head and the alert look flashed on and off. It stuttered, "I know w-what I'm doing. But I—I can tell only what has happened to my charge, n-never what will!" The Sitta rumbled bewilderedly. "Anticipation is beyond my capacity. The child is hurt and hungry. Please come in and help me."

Triumphantly, Amantha followed the robot into the house toward the nursery. She whispered to Ethan, "Sittas ain't smart. I reckon he never heard a bunch of babies together. If one cries, they all do."

The Sitta barred the path. "You seem sincere and are obviously an expert. But before you go in, understand this—attempt no harm to the being in there. I'm linked."

"You'll be unlinked if you don't stop acting balky," warned Amantha. She ducked under his arm and darted toward the crib.

"By linked, I mean that if anything happens that I require aid to handle, an alarm rings in Sittas Circle and help is on the way. Meanwhile, I can put out fires or carry him unharmed through concrete walls."

"Go ahead, run through a wall," invited Amantha abstractly, snatching up the child. "The darling's wet, too. Fetch me a diaper."

The robot fetched at her command. And when the child was quiet, even cooing, but with a sharp undertone of protest, Amantha settled back. "Now we've got to feed him."

"They didn't give me special instructions and I can't originate. If you hadn't come, I'd have had to contact a doctor."
