What was the most important thing in Babara’s life?

Babara always wanted to be a singer. Music was the most important thing in her life,
but to tell you the truth, she had a terrible voice. She took lessons for years, practiced
every day, but in spite of all this, her voice didn’t improve. Honestly, it didn’t get better; it just got louder.
Her teacher finally gave up and stopped teaching her but Babara went on practicing singing, and one day she decided to give a concert and invited her former teacher to attend.
    The teacher was very worried about what to say after the performance. She knew it would be awful and it was. She didn’t want to tell a lie, but she didn’t want to hurt Babara’s feelings, either. Finally she got an idea and went back to the stage to greet her former student.
    "Well, "said Babara, "what do you think of my performance?"
    "My dear, "said the teacher," you’ll never be better than you were tonight."
