Funny conversation between the boys

This evening the kids and I went for a walk while Mike went to get some work done on the van. On the way home the boys had the funniest conversation. It went something like this:

Grant (who was dressed up as Santa Claus): "Santa's just your imagination."
Aaron: "No, he's real!"
Grant: "No, he's just your imagination."
Aaron: "Then who brings us our presents?"
Grant: "Santa."

:) Innocence prevails!
