Thanks for all the kind words everyone. I forgot to add that after that day, I asked him if we could sit down in the coming weeks to dig through his pictures. I expressed how I wanted to hear all about everything and he was very open to having me come over to dig through old photos, etc. After that happens I plan to either record it all somehow, or just jot notes down while we're talking so that I can write up a paper about my grandpa's history. That way, my aunt and 3 uncles, plus 18 cousins can realize how much he did for all of us.
