I am sorry teacher

The day, I made my teacher angry. Of course I didn't want to make my teacher angry with me, but that day I was very very tired. So I slept in class, and I didn't know that He feel sad. usually He was happy, and when I slept in class He don't angry me. He just make me introverted everyone in class. but that day He look so angry at me. And He made me standing in the class for twenty minutes and he said bad words to me. I was very afraid. And after that I was crying. I said sorry to teacher. and I ran out from class. " I am sorry teacher. Please, stop to angry me", I sound in my heart with my tears.
