Sort of off-topic, but sort of related:
I was at the grocery store last night. The bagger asked the cashier "How do you say goodbye?" I was curious what language they were referring to.
He said "Au revoir." OK, French, got it.
She said "Au like A-U?"
I'm surprised she knew the correct spelling of the word if she'd never studied French. Alternatively, I'm surprised she didn't know how to say goodbye if she had studied it -- that would be something you'd learn during the first week, I'd expect.
