"What's rocketry?"

Afen beams at her. "Rocket engines are a kind of engine that works by expelling exhaust from one end, which makes them go fast in the other direction by an interesting principle of physics. They're useful because there aren't a lot of ways to move in space but rocket engines work fine in space - more efficiently than in atmosphere, even."

"Why more efficiently?"

"If you are trying to move through the atmosphere the air will slow you down. If you are trying to move through space there is nothing to slow you down."

"Huh."

Grandparents are glad that she's healthy and okay! They eat brunch and admire her and suggest things she could go see in the city. The zoo! The children's museum! This park! That park! This water park!

Those things sound fun!

"Have you found a nanny yet?" asks Kan's mother.

     "We have some interviews lined up next week."

"What is a nanny for?"

"Playing with you during the daytime once the two of us have to go back to work!"

"You could just get me more books."

"We can also get you more books."

"Good."

"Which ones are your favorite?"

"I like The Rabbit War."

"Ooooh, that sounds like a fun book."

"The rabbits lose."

"People are smarter than rabbits."

"Yeah."

"Does that make you sad, sweetie?"

"I don't want to be as dumb as a rabbit."

"It would not be very fun."

"I hope rabbits are not bored all the time because they're too dumb to do anything cool."

"I don't think so. That would be a shame."

"Yeah. Why aren't they bored?"
