Everyone should be polite. Polite people show good manners. Moreover, they are popular. On the other hand, rude people are looked down upon. Rudeness shows poor education. Therefore, why not be polite? A simple "Please," "Thank you," or "You're welcome," can make a big difference.
每个人都应有礼貌。有礼貌的人展现良好的风度。而且, 他们受人欢迎。另一方面, 无礼的人则遭人轻视。无礼表示教育差。因此, 何不有礼貌一点呢？“请”、“谢谢你”或“不客气”这几个字虽很简单, 却会使情况大不相同。
