方舟济河

There were two boats sailing on the river. If an empty boat clashed into them at this time, the people on the boats would not be angry even they were narrow-minded.

But, under another circumstance, if that boat carried one or more people instead of being empty, the people on those two proceeding boats would definitely ask that boat to give way to them. Once not answered, they would call and ask again. At the third time, there would be some abusive words. Know why? They were angry and utter out such words because they knew there must be some people on that boat.

河面上并行着两支船。这时，如果有一只空船撞过来，即使是心胸狭窄之人，也不会有丝毫怒气。

但是，如果这次船上有人，那么，前行的两条船上的人一定会打招呼，要来人将船撑开。假如喊的一次对方不听，他们肯定会再喊一次，待到喊第三次，其中必定会有辱骂声相伴了，他们之所以前一次不生气而现在生气，是因为原来是空船而现在船上有人。
