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?
Boardgames! I used to be more into trading card games like Magic, but got tired of the cost and constant churn, and then spent the last couple years delving deeper into boardgames, including hosting a weekly game night that regularly has 8-10 people :)
