It is said that elderly teachers should be particularly qualified and patient with students. However, in the last semester of sophomore year, one of our professional exams was old, but she was particularly irresponsible in giving lectures. She thought she was a professor. Sometimes we hand in our homework late, and even every student has to go to her office to do it. Is the shelf a little too big?

Somehow I feel that people her age always discriminate against girls, and she doesn't like to communicate with female classmates in our class, but always likes to chat with several boys in our class. I don't like her very much. Later, because of her own heart knot, she gradually took classes in other classes. Then we had a new teacher, who felt that she had bid farewell to her particularly boring courses and saved our professional teachers' careless attitude in time.
