Society like a huge machine, and individuals are the components of this machine. Just like lubricating oil is necessary to a machine in good condition, polite is also important to society.     The ways used for communication differ from person to person. And these ways paly a big role at communication. And I totally agree that people should treat people in a polite way whatever the conditions. Because it is polite that can solve problem, solving problem with impolite way just aggravate the problem.     As some particular jobs like manager, a good mood is required, that means talk to people especial the employees in a polite way. Even the employee do something wrong, rigorous reprimand could not make him doing better in the future. In contract, when the employee has a negative emotion he can’t concentrate on his tasks. And it is possible that he would bring the bad mood to his co-workers. As a result, the whole company's efficiency goes down. That is the fail of the administrator undoubtedly. So the polite is important to the managers. With polite, individuals can communicate better and make a united group which is powerful.     In our life we can always see people response others' impolite behavior rudely. But the bad consequences follow. Just few days earlier, when I take bus to school, I saw someone in a hurry and push the man next to him to get out the bus. The man who was pushed felt anger and then argued with the man who just pushed him. Finally they almost fight against each other. It is clearly that the man in a hurry even cost more time on the way and both the men had a bad day. We can image that if both of them use a more polite way, use words like "excuse me" and take each other's conditions into account, they could have a wonderful day by enjoying the feeling of help others.     As far as I am concerned, there is nothing is more important than a good manner. That not only make people around you feel happy but also make you taste the feeling of be respect by your polite behaviors.
