Little boys, trains they may be

Ben is constantly pretending that he is a train or a backhoe these days.  I asked him what his hands are when he is a train and he told me that one is for pulling cars, the other for pushing him.  I then tried to introduce him to the push-me-pull-you from Dr. Dolittle, but he didn't go for it and just went back to being "Thomas." I'll take my little "Thomas" for now.
