Ride the Tractor?

Today we are heading out to grandma's house for the annual harvest party.

As we were eating lunch today, I said to Christian,"You better eat your lunch if you want to go ride the tractor at grandma's house."

Here's how the rest of the conversation went:

Megan: You want to ride the tractor with Uncle Andrew, don't you?
Christian: No, with Uncle Shawn.
Me: Uncle Shawn is watching race cars today.
Christian: Race cars?
Me: Do you want to go watch race cars sometime?
Christian: Yah...(with a big grin!)
Me: If you want to ride in a tractor today, it will have to be with Uncle Andrew.
Christian: No, Uncle Shawn.
Me: No, Uncle Uncle Andrew
Christian: No, Uncle Shawn.
Me: What about Uncle Shane? You want to ride the tractor with him?
Christian: No, I ride combine with Uncle Shawn!
