The last Thursday I in your class performance, I am very sorry.
In fact I just because of you let us discuss the topic with some new ideas, to share with other students, but forget you in class. Because before the course instructors, the teacher may be given to us is relatively small, also do not have emphasized to us class discipline, as we move into the senior high school, the teacher of our requirements more stringent, I'm really sorry not according to your request to do. More important is not respect you, didn't respect you in the class paid work. I won't do it again.
For the class gives your explanation, I admit I may as part of the sentence do not understand and give an irrelevant answer
