One day, a little boy named Tim went for a walk. He saw a big tree and wanted to climb it. Tim felt excited and started to climb. As he went up, he felt a little dizzy. He stopped and took a deep breath. Tim saw a bird's nest on a branch. He wanted to see the baby birds inside. But as he moved closer, he began to stumble. Tim tried to hold on tight, but he slipped and fell down. He landed on a soft pile of leaves. Tim looked around and saw a wreck of an old toy car. He picked it up and brushed off the dirt. Tim felt happy to find a new toy. He ran back home to show his mom and dad. They were proud of their brave little boy.
