the happiness of memory There is a story widespread,maybe you have heard about it.It's probably mean that .Someone interviewed some old people,asking them what's the most regretful thing in they lifetime.they said something.then,go through a count,he made a discovery. He founded that all the people regret about the things they never done,but not the things they have done before. Maybe you have done something wrong,but you will not regret about it if only the time is long enough.what you regret is that you did not speak out when you can tell the girl you love her. I saw a TV show a few days ago,The Japanese television interview an old man,let him say something to himself forty years ago.The elderly then speak to the young person he imagined:"Don't go blind,you will not admitted by two university you dreamed of.But the female colleague you particularly love,ask her to marry you at once!Because she will die three years later by the terminal illness。“The elderly cry and shed bitter tears in the end,all the people was deeply touched。 I believe the research about regret is true.I believe that people truly regret about the things they never done when they look backward to his whole lifetime.
