This was my grandma. She married a Quebecois man who was ESL and raised his french kids from a previous marriage all while refusing to ever utter a single syllable in their language. You could ask her anything in french and she would clearly understand and respond in english. She spent sixty years living with and loving french speakers but she never slipped, not even a bonjour. She also refused to ever say why. We waited until my grandfather passed to bury her ashes because we were certain if we left her alone at the family plot in rural Quebec she would find a way to make us regret it.
