I was not able to handle such situations well as a student.My husband was a strong fellow as a student too. He always had guts to say things right on the face. He tells us few of his experiences. One goes like this, his teacher used to take liberties with him, he used to take things but the day he felt that enough is enough. His teacher was supposed to go out of station and he wanted few students to do him a favor by staying at his house and keeping guard for few days. Every one was uncomfortable, but my husband got up and told that he won't be able to stay as he is a student not a guard. This did a little damage but it was a good lesson for the teacher.
