Don, I think Chicken Teriyaki was a highly skilled but easily frightened Japanese cook. Why, when a friend's dog starts sniffing in places it shouldn't be sniffing, does the friend invariably say "that means he likes you"? Are you supposed to be flattered by the attention of the hound? And would it be etiquette to return the act to show that you like it back? Do you risk offending him or his owner by not doing so?
