Once upon a time, there was a little boy named Tim. He loved to listen to music. Tim had a big, fierce dog named Max. They played together every day. Tim knew that one day, the music would end.
One day, Tim and Max went to the park. They saw a big tree. Tim had an idea. He wanted to put a music box in the tree. The music box played Tim's favorite song. Tim and Max were very happy.
The next day, Tim and Max went back to the park. They saw that the music box was still in the tree. But the music was not playing. Tim was sad. Max looked at Tim and knew what to do. Max jumped and got the music box from the tree.
Tim opened the music box and saw that it needed a new key. He found a new key and wound up the music box. The music started to play again. Tim and Max danced and played in the park. They knew that the music would end one day, but they were happy for now.
