    Very often, new-born babies are not beautiful. They are wrinkled (多皱的) or hairless, or they have an

angry look on their faces. They seem to say, "Get away! I hate everybody." But to a parent, that hairless,

wrinkled, angry-faced baby is the most beautiful and perfect child in the world. When that proud father or

mother asks you, "Well, what do you think of my baby? Isn't she beautiful?" What are you going to say? Is

the time for the truth? Of course not!

    You look that proud father in the eye and say, "Yes, she is! She's really a beauty. She's one in a million.

She's going to be a movie star! I can tell! She's as beautiful as a picture."

    In English, this is a white lie. White lies don't hurt people. They are not cruel (残忍的) or angry words.

People use them to make a difficult thing a little easier. When people don't want to meet someone, or eat

something new that they really don't like at a friend's house, they tell a white lie. They are trying to be kind.

They don't want to hurt someone. It's important to be honest, but many people feel that being kind is

sometimes more important.
