Tonight I read the geeklet a story at bedtime, the kind of thing that’s designed to be restful with a hint of mind-broadening moral reassurance. As I finished, he looked thoughtful.

“We wouldn’t be here without this.” He tapped on the floor. “I don’t mean the floor, or the neighbors downstairs. I mean the ground underneath us.”

“That’s right.”

“We also wouldn’t be here without this.” He held up is palm, and this time I wasn’t sure what he meant. “We wouldn’t be here without the sky.”

“That’s also true.” I stood up and turned out the light. “Good night.”

He wasn’t done, though. “The sky wiped out the dinosaurs so we could take over.”

“Mm hmm,” I said, without even a pause. “Good night.”

“Good night, daddy.”
