Santa, redux

We were in the car.

David: I have a question I have been wondering about ALL my life.

I looked in the rear view mirror.

David: Is Santa real?

I looked ahead, wondering... checking the traffic, thinking, thinking.

David: Do they tell you in college?

-pause-

Or do you know when you grow up?

Mom: Well, I think you just know when you grow up.

David: Yea, it's when you grow up. You don't get a present for your kid, and then Santa does, and then you know.
