It was finally time for my teaching debut. Entering a classroom and for the first time stepping up onto the platform, I felt out of place. Even while lecturing, I wondered if I were really cut out for this. The students were a noisy bunch, and sometimes one would call out to me in a loud voice. I had often called out to the teachers in my physics school, but there was a world of difference between addressing a teacher and being addressed as a teacher. The bottoms of my feet began to feel itchy. I'm not a cowardly or timid man, but my nerves unfortunately are not so steady. Each time a student called out to me, I was reminded how one feels on an empty stomach when the noon gun suddenly sounds at Marunouchi. The students didn't hit me with any particularly difficult questions, and I somehow managed to fumble my way through that first hour. When I returned to the staff room Yama Arashi asked how it went. I responded simply that it went okay, and this seemed to put him at ease.
