萍水

真的是除了感动还是感动啊，萍水相遇而已，但是老人却这般的关心！

I was so moved , meeting by chance , while she is this caring to me !

我不知道是什么原因使我开始信任她。她毕竟只是一个萍水友伴，一个我在坐火车途中相遇的人。

I don 't know what made me start confiding in her . She was a chance acquaintance , after all , someone I 'd met on a train journey .

或许她不过和我们一般无二，一起交谈不过是萍水交情，因为城市太大，夜深，或者一起抽烟，看起来也就像朋友。

Maybe she was just like us , talked together was no more than talking , because the city was too big , the night was too heavy , smoking together , may then seemed like friends .
