As a student, how we behave is important to us.
If we behave well, we would be popular among classmates and our teachers are likely to communicate with us.
If not, the situation may go to the contrary. But what are decent behaviors?
First, finish things in time and keep your words. Punctuality and faithfulness are the bases of one's evaluation.
Second, be polite and be ready to help others. The kindness of a people is important.
Besides, do not let yourself or what your do influence others. It's not polite.
Finally, learn to work with others. Teamwork seems more and more important in the modern society.
Working is an essential part in peoples' daily lives. People can judge you through your work.
