Where goin'?

I had this conversation with Brandon yesterday while I was buckling him into his carseat.

Brandon: "Where goin'? Mommy? Where goin'?"
Me: "We're going to the grocery store. Then we're going to pick Nat up from school."
Brandon: "I wanna go Mom-mom an' Pop-pop's house. I wanna go Pop-pop's house, NOW!"
Me: "Oh, we can't go to Mom-mom and Pop-pop's house today. They live far, far away. We'd have to take an airplane to go there, and we have to go pick Natalie up soon."

Thirty seconds later, as we're driving down the street.

Brandon: "Where goin', Mommy?"
Me: "We're going to the grocery store, Brandon."
Brandon: "No gross store! I go air-port!"

I guess he knows he can find airplanes at the airport. Think he misses his Mom-mom and Pop-pop much?
