When it's a friend or someone I've known for a while, I'll make fun of them a little for asking me my nationality, but if it's someone who has the "yellow fever" I'm less nice.
LOL we're so hard to pin down. Who knows what we are?
When I'm in the US, I get Mexican or some kind of Asian.
When I'm in Korea, I get Mexican or Russian or Icelandic. Oh, and once this Puerto Rican guy started talking to me in Spanish (in Korea!!) and when I told him I didn't speak Spanish he said, "What?! You can't speak you're own language?!"
I have no idea.
