With each passing decade, a handful of well-intentioned, but old-fashioned etiquette rules unceremoniously bite the dust. Seriously, when's the last time you questioned whether or not it's appropriate for an unmarried woman to have dinner unchaperoned in a man's apartment, lest she be "ruined" in the eyes of other potential suitors? Social conventions and the rules that govern them are often forced to roll with the times, whether we want them to or not.
