I don't look like an American?

I had another moment yesterday in which a Chinese person had trouble believing I was completely from the United States. When I confirmed for her that I really was born and raised in the U.S., she insisted that my parents were surely [paraphrasing] "from Spain, or some other country where people typically have dark hair, because I don't look like an American." Although it is factually completely inaccurate, my love affair with Spain causes me to be very pleased with her mis-judgment of my ancestry.
