      Alice always wanted to be a singer. Music was the most important thing in her life. To tell you the truth,

she took lessons for years, and practiced every day, but her voice didn't improve. In fact, it didn't get better;

it just got louder.

      Her teacher gave up in the end and stopped the lessons, but Alice refused to give in. One day she decided

to give a concert and invited her teacher to attend.

      The teacher was very worried about what to say after the concert. She knew it would be terrible and it

was. She didn't want to tell a lie, but she didn't want to hurt Alice's feelings, either. At last, she got an idea

and went backstage to greet her student.

       "Well," said Alice, "what did you think of my singing?"

       "My dear," said the teacher, "you'll never be better than you were tonight."
