Music teacher

I was a good student all of my school years. I was quiet and calm always. I wasn't smart enough to study. I was an average student. Science and music were my worse subjects all of my school years. These two subjects were under average always. I couldn't even open my mouth to sing. I never had any trouble and no teacher picked on me except one. The music teacher was unhappy with me and she told my home room teacher, and she gave me a warning the first time. The music teacher complained that I made too much noise in the music class room. I couldn't understand why she complained. The second time, my home room teacher gave to me punishment. I still didn't understand what was wrong with me. After that, I sat in a chair by myself and I didn't talk to anybody in the music class room, before and after class. I was always alone and paid attention to my behavior in the music class room. It wasn't easy, but I wanted to fix that problem. I was totally alone all of the last semester in the music class room. I was in shock when I got my report card. It was the highest grade I got in all of my years in school! I didn't have any communications with any teachers, home room or music. Some times, I think about that situation and I ask myself,"Did I really make noise in the music class room?" I still don't know, but I fixed that problem.
