One day, a boy named Tim went to his attic. He saw a big box. Tim opened the box and found a sour apple. He took a bite and made a funny face. The apple was not good to eat.
Tim heard a small voice say, "Thank you!" He looked around and saw a tiny mouse. The mouse was happy because Tim had found her apple. But Tim did not like the sour apple. He wanted a sweet one.
The mouse had an idea. She took Tim to her secret stash of sweet apples. Tim was surprised and happy. He thanked the mouse and they became good friends. They shared the apples and had a fun day together.
