Today I had an interview for a fellowship (more about that in another post) at 1:40. I teach a class that starts at 2 so I asked a fellow professor if he could cover the first few minutes of my class since we would just be handing out a test and he agreed.
I suppose he told them I would be a few minutes late and when I walked in the class burst into applause that I had arrived. I know they were mostly being silly but it was a nice feeling to have to realize that my students actually enjoy having me be their teacher. They like me they really like me!
