I know it’s an unpopular opinion given current circumstances, but I’ve always been a huge nerd about Russia. The history, the geography, the music, etc. And as an American, I’ve always found it fascinating how U.S.-Russian relations have fluctuated over time. We’ve gone from allies, to enemies, to frenemies. This doesn’t mean I support Z or Putin, of course. What are you a nerd about?
I’m a bit of a grammar/language nerd-- I think it’s interesting to see the different structures of languages and the various ways concepts get communicated. Also by looking at what’s on the level of single words you can get an idea about what’s important culturally.
For example in Japanese, there’s not really a word for brother or sister, you always have to say olderbrother or youngerbrother. That’s because the hierarchy of ages was important enough culturally to get codified into the language.
