When class was over, I almost cried when I thanked everyone for making my teaching experience so rewarding. I was especially touched that a few people specifically came today because they knew it was my last day -- people, e.g., who are generally too frail to be out much. Since I knew it was going to be emotional, I left them a letter expressing my thanks instead of trying to stammer through saying something. When I left, everyone clapped, and several stood up to clap. It really was very touching.
If I'm not in Chicago next weekend, it's going to be weird going to church and not teaching a class.
