My Bad Temper Teacher

Hello, Everybody! I want to tell all of you about my very very good teacher. He is a bad temper person and always blame us. He gets angry easily. For example, One day we had a dictation. And his pronunciation wasn't clear, so I asked him to repeat it again. When he repeated, I couldn't catch the word and I asked him to repeat one more time please...! But I felt nervous. I thought he would become angry and shout at us. Then my thought was true. A bad temper person was turn back and he stared at me with a sharp angry eyes. He shouted at me '' Were you a deaf?'' I repeated to you two times already. Why you couldn't listen even a word? You should go to the hospital to check your ears. I didn't know what to say. I just said I am sorry teacher. But in my heart I thought I wasn't a deaf. Because your pronunciation was not clear. I was no need to go to the hospital, but you should go to check your mouth maybe you always blame us so it had problem now. But it was just my thought. I couldn't say that to him. Just stayed quietly and listened to what he said.
That's all about my very very good teacher. =,=
