>ethnicity you rarely ever see?
Rarely... I was 20 years old when I first saw a black person in real life. This was in a center of a big city, and it surprised me so much that I remember exactly where and when it was.
Nowadays times have changed and it's not that rare in my country - at least in big cities. But I imagine a Croatian farmer seeing a black person - running! - and calling the police to investigate what the hell is going on.
