I find asking personal questions of someone you do not know is rude. My stepson is over seven and a half feet tall and gets asked forever how tall he is. He ignores such questions so then many people turn to whoever he's with and ask them! Other people who look unusual to me are not circus freaks put on earth to entertain me.

I would stay as bland as possible when answering "dumb" personal questions. "What are you?" would get, "A person annoyed at your rudeness" and me walking away. "Where are you from" or "where were you born" would get, "obviously not far enough away from rude, personal questions" or, an incredulous-sounding "Do I know you?" If someone like a policeman asked who I did not want to be quite so pointed around, I'd just say, "here, the US". Followup questions in that direction would be "Rudesville, Kansas" or something.
