There are several times that people encounter different ideas, such as incorrect information or opposite opinion, in class or meeting. When people find that the leader of the room might be wrong, most of them choose to stay quiet since they afraid of being blame afterward. However, in my view, raising the . First, I want to know the fact right away. My idea might not be the correct one, but I want to make sure if I'm right or wrong immediately. For instance, last time, the biology professor was in a hurry of finishing the lesson, so he spoke too fast and thus pronounced a word that has totally different meanings when he was illustrating a theory. Fortunately, I asked the professor right away. Otherwise, the class might understand the theory in a wrong way. Therefore, it is always good to raise question when seeing the mistakes. right away is the best choice for the following reasons. Second, learning to respect others is a polite manner. Listening to ideas of teachers or leaders shows that you are polite and respectful.

She said'"If you expect others to respect you, you should do by yourself from now on." One of the way to respect others is to listening to their ideas even though you feel it is wrong. Consequently, we can discuss with teachers after their class if we really do not agree with their thought. In addition, sharing one's opinion with the leader helps making the idea or theory clear. It is common that one's opinion is everyone's opinion, so the interaction with the leader will help clarify the abstract that the whole room might feel confused as well.

Thus, in the lecture the professor keeps using the confusing words and wait for students to ask him the meanings. This is because he believes that the interaction between the lecturer and the listeners simplify the theory. As the case have shown, challenging the leader at once help the room understand the complex.
