"The french of Rabelais, Racine and Rimbaud....."
My friend’s grandfather used to teach, better to say forced, him and his brother to speak French. It was from some older books. I am not sure as old as Rabelais, but not current. The boys learned as much as they could and then went to Paris. People were laughing at them as, apparently, that was not the language style people spoke anymore. Not that I know much about those differences, but that is what they told me.
