Once upon a time, in a small town, there was a museum. The museum had many nice things to see. One day, a little boy named Tim went to the museum with his mom.
In the museum, Tim saw a big painting. It was hanging on the wall. Tim wanted to touch it. His mom said, "No, Tim. We cannot touch. We can only look." Tim felt ashamed.
Tim and his mom walked around the museum. They saw many other things. Then, they went back to the big painting. But it was gone! Tim looked down and saw the painting on the floor. He had not touched it, but it fell down all by itself. Tim and his mom were surprised.
