The author has written a lovely children's story to help kids confront, in a roundabout and fun way, the issue of immediate gratification, which plagues many children (and their parents ). This issue is related through the story of a boy, Bill, who has a -gimme want want- attitude that is not serving him well. Through the analogy of a pig in a pen, Bill's grandpa teaches him that a pig is best left in its pen, just like the gimme gimme want attitude is best kept contained.

This story is a great way of communicating an important lesson, and parents will surely like the values it is...
