True! One time I was almost hit by a car going way too fast. I tried to slow him down with a wave, but he sped up and perhaps tried to get really close to me, my son and our new puppy! I was able to track down the car in our neighborhood and rang the doorbell. With my son standing next to me we spoke to the owner of the house and told them about what his visitor almost did just down the road. He apologized for his friend, but the actual guy in the car never came downstairs to face me and my son. We were the light and he was hiding out in the darkness, like a true coward.
