What’s the most surreal "small world" moment you’ve ever experienced?

I’m from Singapore, which is a small place, so it was wild to see one of my dad’s close friends testify before the U.S. Congress, then have clips of it go viral online, and later show up at a U.S. presidential inauguration. Going from watching this guy play Mahjong with my dad to all of that was wild, to say the least, lol. Wondering if you’ve ever had any similar experiences.
