There is a piano in the big train station. A sign says, "Please play." It is morning. Many people are in a hurry.
A boy plays one note, then another. A woman sits down. She plays a slow song. The hall is quiet. A man with a bag plays jazz. A girl plays the violin. Then the rush is over. They stop. They nod. A cleaner puts a note on the piano. It says, "Thank you."
