Actually, where I come from ( Karhkiv, Ukraine) ...
We are planning a trip to Ukraine.
I was working on a student dorm in Vicente Guerrero in 2008 when the work foreman's father visited from Canada. His last name was Kozak, and thinking it was how Cossack was spelled in the old country, I asked if his family had come from Russia. His face turned beet red, eyes squinted and - through clenched teeth with strong emphasis on each syllable - responded NOOOO, from Ukraine! 80 years old and built like a steel fire hydrant. Great guy and we laughed about it later.
