When I first saw Norman, the dog, he was standing in the middle of the walkway alone. Looking around. Just standing there. I then saw Bill walking towards him from some distance. As I approached to meet them this group of girls swarmed around to do the same. Norman, it turns out, is a 200 pound, 7-year-old English Mastiff. Bill lives in Chapel Hill and enjoys a daily walk on campus. "When I walk with Norman, it goes much more slowly and is shorter."
