You dash through a crowded railway station, tripping over bags, spilling your coffee, only to have the doors slide shut in your face, leaving you breathless on the platform as the train pulls away.

But at least, if you're in France, someone may be playing the piano for you. But it won't be performed by a paid musician, or even a street entertainer playing for coins. It will just be a random passer-by, jamming (即兴演奏) for the fun of it on one of the pianos that the national railroad company, S. N. C. F. , has fixed in nearly 100 stations across France. They are free for anyone to play, and travelers from all walks of life have taken to doing just that.

Gares & Connexions, the S. N. C. F. division that manages its stations, rents the instruments from producer, Yamaha, which maintains them and tunes them every month or two. The first one was set up in the Gare Montparnasse in Paris in 2012.

The music, mixed with the sounds of shouting passengers, screaming trains and rolling suitcases, gives French stations a special soundscape. The amateur (业余的) musicians have included Irish soccer fans and even babies. In 2014, Gares & Connexions and Yamaha organized a nationwide contest called Your Turn to Play, asking participants to submit (提交) videos of themselves using one of the pianos. It drew nearly 900 entries.

Isn't the railroad company taking a big chance? Obviously not. "None of the instruments has been vandalized to this day, or even merely damaged," said Claire Foumon, a spokeswoman for Gares & Connexions. "They are shared and respected by all. " So if you miss a train in Paris one day, perhaps someone will be playing a favorite piece that will ease your pain. Or perhaps you'll sit down and play your annoyance away yourself.

   It was Thanksgiving morning. I was busy preparing the traditional Thanksgiving turkey when the doorbell rang. I opened the front door and saw two small children in rags（衣衫褴褛）on the top step.

"Any old papers，lady？" asked one of them.

I was busy. I wanted to say "no" until I looked down at their feet. They were wearing thin little sandals（凉鞋），wet with heavy snow.

"Come in and I'll make you a cup of hot coffee."

They walked in and sat down at the table. Their wet sandals left marks on the floor. I served them coffee and bread to fight against the cold outside. Then I went back to the kitchen and started cooking.

The silence in the front room struck me. I looked in. The girl held the empty cup in her hands，looking at it. The boy asked in a flat voice，"Lady，are you rich？"

"Am I rich？Pity，no！"

I looked at my worn-out slipcovers（家具套）.The girl put her cup back in its saucer（茶碟）carefully and said，"Your cups match your saucers." They left after that，holding their papers against the wind. They had reminded me that I had so much for which to be grateful.

Plain blue china cups and saucers were only worth five pence. But they matched.

I tasted the potatoes and stirred（搅动）the meat soup. Potatoes and brown meat soup，a roof over our heads，my man with a regular job，these matched，too.

I moved the chairs back from the fire and cleaned the living room. The muddy marks of the little sandals were still wet on my floor. Let them be for a while，I thought，just in case I should begin to forget how rich I was.
