I sat on the last desk and just watched the teacher teach, how he communicated with the students and how they interacted with him. My first listening lesson took place at 8. A. The teacher did not introduce me, he started the lesson as if I were not there. Nobody asked who I was, they didn't look at me, they didn't whisper to each other, they weren't ashamed. Simply no reaction.
