At a train station in Paris, the city installed a piano for passersby and travelers to play and enjoy. While one man was playing the piano another travelers walked by and stopped. After a moment of hesitation, and without saying a word, he reached down and started playing on the other side of the piano. Soon, the two strangers were performing a concert for the entire hall of travelers who broke out into a applause when the music finally ended.
