A few years ago, I tried something that was to me, a shy person, scary. When I saw a man getting out of a car with a vet plate, I walked over to him, and said, "Excuse me, sir. Are you a vet?" He said, "Huh?" I repeated the question. He said, "Um, I'm a vet. So what?" I said, "Thank you." He said, "Huh?" So I thanked him again. Then he got it. He said, "Thank _you_," and he acquired a large smile. People, I can't tell you how much fun this is. Try it in your own neighborhoods....
