I am running a game of En Garde over on the RPG Stack Exchange. For purposes of verisimilitude, we're wondering about station-specific greetings in Paris in the 1630's. What would be an appropriate greeting between two low-class males with aspirations of climbing the social ladder? What would be a greeting from a low-class to a high-class (but non-titled) male? And what would be a greeting between two high-class gentlemen?
