Very often, newborn 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 ...isn’t she beautiful?” What are you going to say? Is this the time for the truth? Of course not! You look at that proud father or mother in the eyes and say, “Yes, she is! She is really a beauty. She is going to be a movie star! She is 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 to eat at a friend’s house, they tell a white lie. They are trying to be kind.
