Once upon a time, there was a little girl named Amy. She loved to climb trees in her backyard. One sunny day, Amy saw a nice, big tree she wanted to climb. She put her arm on the tree and started to climb up. As Amy climbed higher and higher, she met a friendly squirrel. The squirrel said, "Hi, Amy! Be careful when you climb. You don't want to fall and hurt your arm." Amy smiled and said, "Thank you, squirrel. I will be careful." Amy climbed to the top of the tree and looked around. She saw her house, her yard, and her friends playing. She was so happy. When it was time to go down, she remembered what the squirrel said. So, she climbed down slowly and carefully. Amy learned that it is important to be careful and listen to good advice from friends. And that's the end of the story.
