Existentialism.

On the way home from preschool today, I asked Marley if she knew what an adult is.

"Yes. A parent," she said.

So then I told her that not all adults are parents, and that not every adult chooses to have children.

"But I decided to have a couple of kids, Bean. Aren't you glad?"

"Yes. Because if you didn't, then I wouldn't be living my life!"
