We drink tea every day. But more than three hundred years ago, most of the people in Europe did not know anything about tea, because it was grown in Asia. There is a story about an English sailor(水手). Once he went to India and China. When he came home, he 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 leaves and asked them to eat tea. Of course, nobody liked the tea leaves.

Just then the sailor came in.  He looked at the tea leaves on the table and asked his mother,“What have you done with the tea?”

“I boiled it as you said.”

“I threw it away, of course.” answered the woman.
