I recall a Quebecois girl-friend who took offense to the Queens picture, hanging in my kitchen. When I made the comparison to Quebecois language and culture it was respected. Her mother, took offense later and got told quickly in Quebecois french by the girl friend.....Mama didn't think I comprehended. I recall at Christmas getting a book, english text, from the mama about the assimilation of the Quebec garrison during the years following the Fall of Quebec. I doubt mama had a clue as to the contents. It's called mutual respect.
