I've never been asked what race i am but I do get the what nationality are you query often. Because of my darkish complexion I'm often mistaken for Indian, Mexican, Greek etc. That is until I speak.
Same here, the question about nationality.
My parents and myself turned out a hodgepodge, but when one looks at the grandparents and great-grandparents, the mixture's English, Scots, Welsh, Brandenburgian, Carpatho-Ruthenian, and Judaic.
When asked, I claim that with which I most "identify," English, although the physical characteristics are Welsh and the temperament is most definitely Carpathian.
