Nov. 21 is World Hello Day. It began back in the 1970s as part of an effort to make the world more peaceful. It was created by the United Nations just after the war between Israel and Egypt in 1973. Its aim is to encourage people to use communication rather than force to settle conflicts(解决争端)。 The philosophy (理念) behind it is: Say “Hello” and stop war.

    It sounds like a fine idea, but most of us know that simply saying “Hello” won't bring about world peace. Still, the simple act of saying “hello ”to someone can truly make a lot of difference. You raise your head to someone as you pass by, say “Hello.itis such a casual (不经意的)thing and requires so little effort, but you might even make his day.

    Although we might not realize it, a small thing like a greeting can mean a lot to a person. Some people are lonely because they're shy. That leads to them feeling cut off. They find it difficult to communicate with people, even though they want to. They may secretly smile in their hearts after they hear your greetings. It's a good idea, not just on Nov.21, but every day, to remember to say “hello”to as many people as we can.

    No one said it better than the French writer Joseph Joubert: “Politeness is the flower of humanity(人性)''. A “Hello” to a stranger is a small thing, and often neglected (忽视), but through it we can make the world better for another person.
