The idea that we will make a society where literally everybody is graded, the good at the top, bad at the bottom, exactly done as it should be, is impossible. There are simply too many random factors: accidents, accidents of birth, accidents of things dropping on people's heads, illnesses, etc. We will never get to grade them, never get to grade people as they should.

译文：有仇的冤家应该和睦相处，不应该继续结仇，都回头看下自己的不足。赏析：多一个敌人不是多一个朋友，冤家过多对我们的人生并没有好处。在发生矛盾时，我们都反思一下自己的言行是否得当，各退让一步，天地自然变宽了。

教师最重要的是一颗理解的心，它值得无限地尊崇。人们在回忆中赞赏才华横溢的教师，但感激曾触动自己的人类情感的教师。对于成长中的孩子、对于孩子的灵魂，功课是必须的，但至关重要的营养是人性的温暖。

无人机的应用将无处不在。
