One day,two men are talking at the railway station.The train has just arrived （到达）but they don’t notice it.Then the attendant （乘务员）shouts,“Take your seats,please!”
Hearing the voice,the men run for the train.But only one man gets on the train.The other man is left behind and he looks very sad.
People around him say,“That’s not too bad.At least your friend gets on the train.” The man says,“But it is my train.My friend only comes to say goodbye.”
