I visited Amsterdam recently and took a little TFIOS tour! I started at the library where John wrote some of the book and then went on a hunt to find the places in the book and got to meet another Nerdfighter in the process!
One time man on the street asked me about something in Russian. I didn’t know what he asked me about bc I don’t learn this language so I said “Sorry, I don’t speak English”. Then I realized what I said.
