      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.

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
