Jack: What is that?
Me: It's a...RV...a Winnebago...a motor home. You can go on trips and live in it.
Jack: We should do that next time.
Me: That would be nice on our trip to Maine. (I'm visualizing myself driving a huge RV with Jack, Casey and Tugger wandering around in the back, bouncing off the walls as I hit bumps and swerve to avoid things.)
Jack: Yeah, can we get one?
Me: No, it costs a lot of money to buy one.
Jack: Hmmm...where can we get a lot of money?
(Pause. I can't wait to hear what he comes up with.)
Jack: I know! We can get it out of my piggy bank in my playroom.
He was so proud of himself for solving that problem. Then I told him he would probably need to fill the whole playroom with pennies and quarters to be able to buy an RV.
