Hitting a car in front of her at a red light, then telling the burly man in her high pitched authoritative voice, "It was nothing but a bump. Get back in your car. It's nothing to worry about. Don't call the police, because it was only a bump." And the hefty male driver did just that. He got back in his car and drove off when the light turned green. I couldn't believe it! Don't mess with Grandma!
