Writing prompt: My Teacher

Student essay:
In my middle school life, there are many teachers and classmates. I can't forget them. But a math teacher impressed me most.
The math teacher was an old and gracious woman, but she was also mad because of the wrong things we did. One day, a student played his phone in class, Mrs. Jia was angry with him at first, but then she calmed down and began to tell us a story. When the story was over, everyone was moved. We knew the importance of time and how to make our lives meaningful. Although this class we didn't have any math knowledge, we learned something special. I thought everyone would remember it and thank for her.
In my opinion, students should respect their teachers. Our teachers give us knowledge and teach us how to be a useful person. We should understand them and never forget them. They will always be our teachers in our lives.
