在一家超市里，父亲、母亲、年轻的儿子一家三口在完成了家庭购物计划之后，父亲让儿子将使用过的购物手推车送回到原来的地方。“爸爸，你看到没有，手推车扔得到处都是，没有一个人送还，这也是超市专门雇人负责归拢手推车的原因。”父亲耐心地教导着儿子：“那么，儿子，你认为送还手推车是不是一件有益的事情呢?”
儿子陷入了沉默。短暂的沉默之后，母亲插言道：“这不是什么大不了的事情，别太苛求儿子了，我们回家吧。”
当父亲正要放弃自己的要求时，他看到，一对年迈的夫妇一人推着一辆手推车，将它们送还到了原来的地方。目睹这一情景，父亲再次对儿子说道：“儿子，
这世界上共有两种人：一种人用过手推车后，将它随处一扔了事；另一种人则会将它送回去。我希望你做送回去的那种人。现在，你把手推车送回去吧。”
显而易见，这个故事并不是在探讨送不送还手椎车的问题，它探讨的是一个简单行为背后的价值认知问题。这个故事其实在提示我们，世界上有这样两种人：
一种人总是去做自己认为正确、有益的事；另一种人则是寻找理由不去做这样的事情。 第一种人无疑是可贵的，但更可贵的是，这种人无论别人做不做，他们都会坚定地去做他们认为正确的事情，这并非因为他们认为这样的行为会改变世界，而是因为他们不想让世界改变自己。

Don't Be Changed by The World
In a supermarket, a family of three, the father,the mother and their little son, just finished their family shopping plan. The father asked his son to send the trolley which they used to the place it was. " Dad, haven't you seen these trolleys are everywhere? Nobody sends them back, and that is why supermarkets specially employ people to make the trolleys together." The father instructed patiently his son:" Then, my son, do you think it is an usefull thing to send back the trolley?"
The son sank into silence. After a short silence, his mother broke in:" This is not a big deal. Don't be too strict to him, let's go home."
when he desided to give up his requirment, the father saw an old couple each pushed one trolley back to the original place. Seeing that, father said to his son:" My son, there are two kinds of people: one kind of them put the trolley everywhere after they used; while another kind send it back. I hope you will be the kind of people who send the trolley back. Then, now, you send it back."
Obviously, the problem discuessed in the story is not whether send back the trolley or not, but the awareness to value behind the simple action. What the story tells us is that there're two kinds of people in the world: one kind of people always do what they consider is right and useful, while anthor kind usually don't do such thing by seeking excuse.
The first kind of people is undoubtedly precious, but the more precious is that no matter whether others will do or not, they will resolutely do what they think is right. It is not because they think such action will change the world, but they don't want to be changed by the world.
