“Again?” Claire, sharing the vid viewing chamber with her, said faintly.

“Just one more time,” Silver pleaded. Her lips parted in fascination as the black Persian appeared over the vid plate, but out of deference to Claire she turned down the music and narration. The creature was crouched lapping milk from a bowl, stuck to its floor by downside gravity. The little white droplets flying off its pink tongue arced back into the dish as though magnetized.

“I wish I could have a cat. They look so soft…” Silver’s left lower hand reached out to pantomime-pat the life-sized image. No tactile reward, only the colored light of the holovid licking without sensation over her skin. She let her hand fall through the cat, and sighed. “Look, you can pick it up just like a baby.” The vid shrank to show the cat’s downsider owner carting it off in her arms. Both looked smug.

“Well, maybe they’ll let you have a baby soon,” offered Claire.

“It’s not the same thing,” said Silver. She could not help glancing a little enviously at Andy, though, curled up asleep in midair near his mother. “I wonder if I’ll ever get a chance to go downside?”

“Ugh,” said Claire. “Who’d want to? It looks so uncomfortable. Dangerous, too.”

“Downsiders manage. Besides, everything interesting seems to—to come from planets.” Everyone interesting, too, her thought added. She considered Mr. Van Atta’s former teacher, Mr. Graf, met on her last working shift yesterday in Hydroponics. Yet another legged Somebody who got to go places and make things happen. He’d actually been born on old Earth, Mr. Van Atta said.

There came a muffled tap on the door of the soundproof bubble, and Silver keyed her remote control to open the door. Siggy, in the yellow shirt and shorts of Airsystems Maintenance, stuck his head through. “All clear, Silver.”

“All right, come on.”

Siggy slipped inside.
