题目内容：

The train moved slowly．It was full of bored people．Few of them smiled or talked．

Suddenly a little boy stood up and walked in between adults’(成人的)legs．His father stayed by the door，the boy sat next to the window，with many unfriendly people around．

As the train went into a tunnel，something happened．The little boy got up from his seat and put his hand on my leg．I thought that he wanted to go past me and back to his father，so I moved my leg．But he didn’t move on，the boy kissed(亲吻)me on the face suddenly．

What happened? A kid kissing a stranger on the train，is that right? To my surprise，the boy went on kissing all my neighbors．

I was surprised and of course，not so comfortable．I looked at his father and asked，“Why?”

“He’s so happy to leave the hospital，”the father said．“He stayed there for two weeks．”

The train stopped．Father and Son got off and left．On my face I could still feel the child’s kiss．I felt warm inside．And the kiss made me think a lot．I was glad because I could feel and share the boy’s joy!
