Once upon a time, a little girl named Lucy lived in a small house. She had a very interesting room with a high ceiling. Lucy liked to look at the ceiling and imagine it was the sky.
One day, Lucy saw a tiny mouse on the floor. The mouse looked up at the ceiling and said, "I want to go up there! Can you help me?" Lucy thought about it and said, "I will help you, but you must trust me."
Lucy found a long string and tied it to the mouse. She threw the other end of the string up to the ceiling. The mouse started to climb, but suddenly, it began to rain inside the house! The rain made the string slippery, and the mouse slid back down to the floor.
Lucy and the mouse looked at each other and laughed. They knew the rain was a surprise, but they still had fun trying to reach the ceiling. From that day on, they became the best of friends and always trusted each other.
