Chairs in the car

Tonight Max was playing with his dollhouse (one of those big light wood modern numbers) and he started talking to the little people and then he put them in the big car. (the dollhouse came with a garage and a car).
And then...he took the kitchen chairs out of the house, and loaded them into the car, and the people were chatting and driving along with chairs all stuffed around them.
it was so funny to me. I don't know how many times he has driven with a chair next to him in the back seat, or one in the passenger seat!
My Dad often finds them for me by the side of the road, or at house sales, and we'll drive home from their house with one. and then we'll pack one into the car and deliver it to a show or an event or something.
