I Am From Korea

From mmebonfils.free.fr

It never fails. I teach in Korea and about 99% of my students are from Korea. They are all Korean, but a handful of them were born in China. It gets me when I ask where they're from and they say Korea. It's just not done. If you were back home and people asked where you were from, you'd name a city or area. If you're talking in Korean, you'd do the same.
Yet you could go around an entire class and ask students where they were from and they'd all say they were from Korea. I'm not sure whether to laugh or cry!
