So, back then I was 17, just started my sociology undergrad in Armenia, and there was this World Congress of Sociology happening at my university in Armenia and Wallerstein was present. I just got back from US after studying one year in high school, so because of my English skills I was approached to volunteer and help guests. For the opening ceremony, I approached his wife and him and asked to take front row, he kindly refused, saying he is fine sitting in the back as well. He also gave a lecture for the students and we interacted at the sessions. Amazing memories. Back then I didn't even realize how big he is!
