Tara and Beth met in a dancing class and became close friends very quickly. Soon Beth felt comfortable talking to Tara about her own problems, and Tara was always happy to listen to her. One day, Beth heard some other girls talking about the things that only she and Tara knew. Later, Beth found out that Tara was talking behind her back. Beth didn't understand how Tara could be so nice when she was with her, but be a different person when they were not together. The next day at school, Beth started saying bad words about Tara. From then on, when they met, they both said bad words about each other.

    It was clear that Tara was not a very good friend to Beth when she talked behind Beth's back. Why did Tara start doing this? Was she not a nice person? Maybe not. There might be something else going on.

    At last, Beth found out that Tara's problem came from jealousy(嫉妒), because Tara didn't have nice clothes or expensive things like Beth's.
