覆水难收的启示？很急很急！！！！！！要演讲的！！！！！！！

There is a west saying:’ It is no use crying over spilt milk’, which means what is done cannot be undone. From the saying we can learn that, if you want to say something, you should think over whether the words would hurt somebody, since you can not take back your words. Before you do something, you should also think carefully. Otherwise, you would hurt others or yourself.
