That's the thing. Is it a conversation, if someone next asks you "No, but where are you from?".
The flaw in your reply is that you say the conversation "progresses". Has the conversation progressed, if someone asks "No, but where are you from?" when you gave your one word answer?
If you find it hard to understand, run yourself through this conversation:
Q: Where are you from?
A: Kerry.
Q: No but where are you really from?
A: Kerry.
Q: Okay fine, I'll ask differently then, what Nationality are you?
A: Irish.
Does that happen for you? I can bloody well tell you it happens to me, and any other non-white British person.
Presuming that fictitious circumstance I mentioned previously, where your parents may have been born in Scotland, but had been born, raised and spent your whole life in Kerry, would you answer those questions differently? Would you get annoyed that someone just doesn't accept that answer?
It's not "narrative". It is something that has happened to me week after week, my whole life, and to other non-white British people, who often have never set foot outside the UK to their "native" lands...
