the curent  students who are advancing for future generations need to have good history with everyone.  Besides, there are a few people who go against that.  So what is behavior?  Behavior is the process of communicating, handling, solving immediate problems and talking to others in the community.  Behavior must have self-esteem, courtesy and modesty to both please listeners and at ease what you say.  Among today’s students, there are some very good native students.  The teachers who come are the students who cross their arms to greet and speak politely.  Friends in the school talk openly and sociable.  But in school there are people who speak and behave that make us unhappy.  Some of them used swearing words, such as hitting the ear, talking very impolite, causing disunity with everyone around. Behavior is the measure of the student.  A student who behaves well is always loved by his friends, respected by his teachers, and appreciated by everyone.  People who do not behave well later on will not have anyone by their side, becoming people who are not useful to society.  Therefore, we must know how to use words and behave well and stay away from rude words, unacceptable actions so that everyone can be closer Student behavior is essential for us  right now.  We must try our best to practice dealing with people, speaking easily, studying together to become useful citizens of society.
