The French language, cont’d

Reading my“Language Police” post below, Papa Castel writes to remind me of a story from my adolescence…
We were walking down Seventh Avenue in New York together and peered at the menu in the window of a très chic French restaurant. Pop (who by the way, teaches languages professionally) wondered aloud what on Earth “boeuf haché au fromage” might be.
I looked at him, puffed up on my high-school French, and said, “Dad, it’s a cheeseburger.”
