Imagine this hypothetical, you and I make plans to play tennis. Initially, we meet at your home and we travel to a tennis court. I have a bag slung over my shoulder and carry a tennis racquet in my hand. We get along well but haven’t seen each other for months. As we walk towards the tennis courts and pass many people, I reach back with my racquet smack someone squarely on the face and continue walking as if nothing occurred. This stuns you. You are shocked; you know me to be a reasonable person. This is not anything you can comprehend. I still have the racquet in my hand, so you’re reluctant to say anything. We continue walking.
As we make our way to the courts, we pass many more people. However, you’re still in stunned by the event that transpired. As your mind is racing and contemplating what you should do, I again reach back and this time I strike someone squarely on the knee. They collapse on the ground and cower in fear. You are still in shock and continue to walk but put more distance between us. This continues.
