In Karen Hesse's Out of the Dust, playing the piano makes Billie Jo very happy. Her family was really unlucky, her mom died and her dad was sad and sick. The only thing could made her happy was playing the piano. When she plays piano, she throws all unhappy things off. Although I don't play the piano, I understand how Billie Jo feels. It's the same way I feel when I play my electric guitar. I turn up the volume and play my favorite song. At that time, I forgot all the unhappy things. I only felt the hunger for playing music. Only felt happy.
