This reminds me of a story. A friend of my daughter had a gerbil. Her family had a great Dane(you can see it coming, can't you). The family habit was to watch TV together. They had done this many times before. The girl in front of the TV with the gerbil and the Dane laying contentedly at Dad's feet watching the gerbil. The gerbil ran towards the dog, the dog's mouth opened and the gerbil was a TV snack. It just makes me wonder, What if those bars weren't there?
