When You Skip the Good-bye
The restaurant or the living room is full of people you adore: your parents, your childhood best friends, your college roommates, your nephews or cousins. So it makes no sense to anyone at all when you edge out of this gathering and slip out the front door without a word. Some might say that you just don't like good-byes or that it drives you crazy to run around the room announcing your departure to everybody, which only delays and prevents any actual departing. But mostly, it's just that you want to leave the room just as it is it—perfect, not a single word or gesture to imply that what's happening there will ever end.
