If I asked you "Who are you"? Would you know what to say?
I would describe myself differently depending on the person asking. None of the descriptions would complete.
I always love that one.
looks like you're saying ..."May I have this dance?" hahahahahaha
Elaborate on the question if you'd like me to elaborate on the answer because that's both a simple and complicated question.
Yes, I'd know what to say: "Why do you ask?"
Such a question as "who are you?" can have different correct answers depending on context. Sometimes even "none of your business" is a correct answer.
