你不会为了同一个笑话一遍又一遍的笑

一天，一个演讲者讲了一个笑话，在场的所有观众都笑了，他又把这个笑话讲了一遍，这一次，笑的人比较少了。然后又一遍一遍的重复讲这同一个笑话，直到没有人笑。他笑了笑说，你不会为了同一个笑话一遍又一遍笑，那为什么一遍一遍地为了同一件事哭泣呢？

One day, a speaker told a joke Everyone in the audience laughed. He told the same joke again. This time. less people laughed. And he told the joke over and over again. Untill nobody laughed. He smiled and said, you can't laugh at the same joke over and over again. Then why would you keep crying over the same thing over and over again.
