Etiquette is a code of behavior that influences expectations for social behavior according to contemporary conventional norms within a society, social class, or group. Rules of etiquette are usually unwritten, but aspects of etiquette have been codified from time to time. Rules of etiquette encompass most aspects of social interaction in any society, though the term itself is not commonly used. A rule of etiquette may reflect an underlying ethical code, or it may reflect a person's fashion or status.
