When I was in third grade; I had a very good class teacher. He treated me as I was his son. At that time I was not very good at lessons especially in math. I could never get good grades on math exams. Although he was teaching nice; I always failed on math exams. One day our director came to our class. At that time our class contained almost 65 students. It was quite crowded and it needed to be divided into two parts. He informed us that there was going to be a new class in the school and a teacher was hired to teach the new class starting from next Monday. They were going to divide the number of students by looking at the class list. They told that they are going to take students starting from number 40. And I was the fortieth student in the class. So I was going to be taken to the other class and be separated from my friends and my teacher. It was a big shock for me. I could not stand it. I insisted on my parents to call the teacher and change someone else instead of me. My parents were saying that may be the new class would be better for me. But I made them call the teacher. Although they called the teacher, and asked for it the teacher told that it would not be fair and others would ask for the same and he refused it. I was too disappointed to hear it. But I did not have any other choice than going to new class. I was always thinking that the new teacher would be a very rude and a bad person. I had prejudices until I saw her. When I saw her, I understood that she was not a bad person and she was teaching math very well. Our class was better now and teachers could help students more because of less number of students. I was listening to her very carefully on math lessons. After one week, we had a math quiz and I did quite well on the quiz. When I learnt that I got full points on the quiz two days after the quiz I was very ashamed of myself because of having many prejudices about my new teacher.
