Second: It's not very culturally different from Poland. I guess eastern Ukraine is. Western Ukraine (for reasonable historical reasons) is not.
Third: so I'm a bit Ukrainian. Okay. Given that it's 80% just like home, I'm not sure if I learned anything. I mean, the guy I stayed with in Lviv was (entirely coincidentally) an almost-coworker at Google. I've seen some old-style houses in Ukraine and in Poland at cultural museums. All this ancestor-following kind of confirms what I imagined: in Poland/Ukraine it's dark and rainy and you make fences out of bent slices of wood because nails are too expensive; in Italy it's beautiful and you hang out on piazzas and drink wine. (guess stereotypes exist for a reason?)
Fourth: well of course people who lived 100 years ago don't have much bearing on my life now. It's just cocktail-party interesting, like Myers Briggs tests or astrology.
