One day, a young girl named Lucy went to her friend Tom's house to play. They saw a big bookcase with many books. They both stared at the bookcase, thinking about which book to read.
Tom said, "I want to read the book on the top shelf." But the book was too high for them to reach. They tried to jump, but they could not get the book. Lucy and Tom felt sad.
Later, Lucy had an idea. "Let's use a chair to stand on!" she said. They put a chair close to the bookcase and climbed up. They got the book and read it together. They were happy now, and they learned that they could solve problems by working together.
