The subway train moved back and forth, its wheels producing more loud sounds than ever against the tracks. Outside the window was just the  21  cold of winter. The carriage was filled with frozen self-centered, bored  22 .

Suddenly a little boy  23  his way in between grown-up legs.  24  his father stayed by the door, the boy sat next to the window, surrounded by  25 , half-awake adults. What a brave child, I thought. As the train entered a tunnel (隧洞), something totally  26  happened. The little boy slid down from his seat and put his  27  on my knee. For a moment, I thought that he wanted to go  28  me and returned to his father, so I moved a bit. But instead of moving on, the boy held his  29  up towards me. He wanted to tell me something, I thought. I  30   to listen to what he had to say. Wrong  31 ! He kissed me softly on the cheek.

Then he returned to his  32 , settled down and cheerfully started looking out of the window. But I was  33. What happened? A kid kissing an unknown grown-up on the train? To my amazement, the kid  34  to kiss all my neighbors. 

Nervous and puzzled, we looked questioningly at his father. “He’s so happy to be  35 .” the father said. “He’s been very sick.”

The train stopped and the father and son got down and  36  into the crowd. The doors closed. On my cheek I could still  37  the child’s kiss -- a kiss that had caused  38  soul-searching. How many grown-ups go around kissing each other  39  the joy of being alive? How many even give much thought to the privilege of living? What would happen  40  we all just started being ourselves?

The little boy has given us a sweet but serious lesson: Don’t let yourself die before your heart stops!
