We drink tea every day. But more than three hundred years ago most people in Europe did not know anything about tea. Some people had heard about it, but very few of them knew what to do about it. There is a story about an English sailor who went to countries in the west, the east and the south. He had been to India and China. One day he came home and brought some tea as a present for his mother. She told her friends about the present and asked them to a "tea party". When her friends came to the "tea party", the old woman brought out some tea-leaves and asked them to eat. Of course, nobody liked the tea leaves. At that time, the sailor came in. He looked at the table and said, "mother, what have you done with the tea " "I boiled it as you said." "And what did you do with the water " "I throw it away, of course," answered the old woman. "Now, you may throw away the leaves, too," said the sailor.
