Big Yellow Truck

David felt ingenious one day when he figured out how to turn the big yellow truck into a "trailer".

Thanks, buddy, for asking first before you put your sister in your "trailer" for a ride. 

And thank you especially for obeying me once I said "no."

So he found the next best thing to do with his big yellow truck:

he got his sister to give him a ride in it.

As often as he could, he encouraged the little engine to push him around.

 And she could!!!
