Once upon a time, there was a little girl named Lily. She loved to read books and she had a big bookshelf in her room. One day, Lily wanted to read a book about a happy princess, but she couldn't find it on her bookshelf. She looked and looked, but it wasn't there. Lily was sad, but she decided to solve the problem. She looked under her bed and in her toy box, but the book was nowhere to be found. Suddenly, she heard a noise coming from her closet. She opened the door and saw that her little brother had taken the book and put it on the top shelf! Lily was surprised, but she was also happy to have found the book. She climbed up the bookshelf and grabbed the book. From that day on, she made sure to keep her favorite books in a safe place where her little brother couldn't reach them.
