Politeness is a good tradition in our country. No one likes rude people. It is important for us to be polite. We should be a polite student.
As a polite student, we shouldn't talk in class. If we have any questions, we should raise our hands. We shouldn't talk loudly between classes either. I think it is impolite to be late for class. When someone is in trouble, we should not laugh at them. We should always say "please" and "thank you".
If everyone is polite to others, the world will be better and better.
