Literally Lost In Translation

(All of my siblings have taken French in high school. My brother is singing a song in French, pauses, and looks at me.)

Brother: “‘Que sera, sera. Whatever will be, will be.‘ Hey, [My Name], what does the French part mean?”

Brother: “No, the French part!”

Brother: “Oh, my god! You learn something new everyday!”

Me: “The translation is in the song…”

Brother: “But the French part…”

Me: “You took French.”

Brother: “So?”
