Outer space

I picked K up at school today. His class is learning about the solar system.
Some of the things he's learned:
Outer space is far away. It's not in Chicago. It comes out at night.
K can't be a space ship driver, because he made a space ship driver hat in school but now he deosn't know where it is.
When he grows up, he will be a Daddy, because his Daddy will be old and then he'll die, so Kivi and Donny will be the Daddies and take care of Mommy.
And who will be the Mommy who takes care of Mommy?
K thought about that for a while. "You will," he finally told me.
