Dear Mary, I am not happy these days. I am new in this class, you know, but I don' t have any friends here. I always have to keep quiet and put my heart into my study. I thought things would be fine. It's very hard for me to be happy and sometimes I get lost in thought. So I can't follow the teacher. I know it is not right like this, but I can't control myself in class. Then my study is bad now. Some students make fun of me. I feel hurt , but I don't show my anger. In fact, I have to hide  my unhappiness. I feel terrible. Dear Mary, I really don't know what to do now, Can you help me? Yours, Jane ,A, B, C, D,, . Why is Jane sad?
Her classmates are good to her. She has no friends at the old school. She has no friends at the new school. She doesn't like her school.
