At any rate, the elephant was little in the beginning, like a lap dog. The young son kept telling his parents there was an elephant in the house, but they wouldn't believe it. So the elephant kept growing, trying to get their attention. Finally, he was so big he could walk off with the house. At that point, the parents acknowledged the existence of the elephant and he began to shrink back to his initial little doggy size. Obviously, the story was about problems being ignored that just get bigger unless they are acknowledged.
