    When you meet someone for the first time, you will get a quick idea in your mind of that person in the first moment. Your feelings about other people, however, are really just show the way that you look at yourself.

    So you can allow others to be the mirror to see your own feelings of self-worth more clearly. And, you can see the people you don't like as mirrors to show you what you are not accepting about yourself.

    To live peacefully with others, you will need to learn patience. A big challenge is to let your judgment of others be a lifelong research of yourself. Your task is to consider all the judgments you make onto others carefully and to begin to see whether you can use them to help yourself to become better.

    Several days ago I had a business lunch with a man who showed objectionable table manners. My first feeling was that he was impolite. When I noticed that I was judging him, I stopped and asked myself what I was feeling. I discovered that I was nervous to be seen with someone who was eating with his mouth open.I was very surprised to find how much I cared about how the other people in the restaurant judged me.

    Remember that your judgment of someone will not stop you from becoming like him. Just because I think my lunch partner impolite, it does not prevent me from looking or acting like him. In the same way, my patience to him would not make me eat food with my mouth open.

    When you get close to life in this way, those whom you hate and those whom you love can be seen as mirrors, guiding you to discover parts of yourself that you dislike and to accept your greatest personalities you are proud of.

                                                                                                                            那夜，那对盲人夫妻
        ①我永远记得那个夜晚。悲怆的声音一点点变得平和，变得快乐。因为一声稚嫩的喝彩。
        ②那是乡下的冬天，乡下的冬天远比城市的冬天漫长。常有盲人来到村子，为村人唱戏。他们多为夫妻，两人一组，带着胡琴和另外一些简单的乐器。大多时候村里唱戏会很晚。在娱乐极度匮乏的年代，那是村里人难得的节日。
        ③让我感兴趣的并不是那些粗糙的表演，而是他们走路时的样子。年幼的我常常从他们笨拙的行走姿势中找到属于自己的卑劣的快乐。那是怎样一种可笑的姿势啊！男人将演奏用的胡琴横过来，握住前端，走在前面。女人握着胡琴的后瑞，小心翼翼地跟着自己的男人，任凭男人胡乱地带路。他们走在狭窄的村路上，深一脚浅一脚，面前永远是无边的黑夜。雨后，路上遍布着大大小小的水洼，男人走进去，停下，说，水。女人就笑了，不说话，却把胡琴攥得更紧。然后换一个方向，继续走。换不换都一样，到处都是水洼。在初冬，男人的脚，总是湿的。
        ④那对夫妻在村里演了两场，地点在村委大院，两张椅子就是他们的舞台。村人或坐或站，聊着天，抽着烟，跺着脚，打着呵欠，一晚上就过去了。没有几个人认真听戏。村人需要的只是听戏的气氛，而不是戏的本身。
        ⑤要演最后一场时，变了天。严寒在那一夜，突然蹿进我们的村子。那夜滴水成冰，风像刀子，直接刺进骨头。来看戏的人，寥寥无几。村长说要不明天再演吧？男人说明天还得去别的村。村长说要不这场就取消吧？男人说，说好三场的。村长说就算取消了，钱也是你们的，不会要回来。男人说没有这样的道理。村长撇撇嘴，不说话了。夫妻俩在大院里摆上椅子，坐定，拉起胡琴，唱了起来。他们的声音在寒风中颤抖。
        ⑥加上我，总共才三四名观众。我对戏没有丝毫兴趣，我只想看他们离开时，会不会被冰的水洼滑倒。天越来越冷，村长终于熬不住了。他关掉村委大院的电灯，悄悄离开。那时整个大院除了我，只剩下一对一边瑟瑟发抖，一边唱戏的盲人夫妻。
        ⑦我离他们很近，月光下他们的表情一点一点变得悲伤。然后，连那声音都悲伤起来。也许他们并不知道那唯一的一盏灯已经熄灭，可是我肯定他们能够感觉出面前的观众正在减少。甚至，他们会不会怀疑整个大院除了他们，已经空无一人呢？也许会吧，因为我一直默默地站着，没有弄出任何一点声音。
        ⑧我在等待演出结束。可是他们的演出远比想象中漫长。每唱完一曲，女人就会站起来，报下一个曲目，鞠一躬，然后坐下，接着唱。男人的胡琴响起，女人投入地变换着戏里人物的表情。可是她所有的表情都掺进一种悲怆的调子。他们的认真和耐心让我烦躁。
        ⑨我跑回了家。我想即使我吃掉两个红薯再回来，他们也不会唱完。我果真在家里吃掉两个红薯，又烤了一会儿炉子，然后再一次回到村委大院。果然，他们还在唱。女人刚刚报完最后一首曲目，向并不存在的观众深鞠一躬。可是我发现，这时的男人已经泪流满面。
        ⑩我突然叫了一声“好”。我的叫好并不是喝彩，那完全是无知孩子顽劣的游戏。我把手里的板凳在冻硬的地上磕出清脆的响声。我努力制造着噪音，只为他们能够早些离开，然后，为我表演那种可笑和笨拙的走路姿势。
        ⑪两个人同时愣了愣，好像他们不相信仍然有人在听他们唱戏。男人飞快地擦去了眼泪，然后，他们的表情变得舒展。我不懂戏，可是我能觉察他们悲怆的声音正慢慢变得平和，变得快乐。无疑，他们的快乐，来自于我不断制造出来的噪音，来自于我那顽劣的喝彩，以及我这个唯一的观众。
        ⑫他们终于离开，带着少得可怜的行李。一把胡琴横过来，男人握着前端，走在前面，女人握着后端，小心翼翼地跟着，任凭男人胡乱地带路。他们走得很稳。男人停下来说，冰。女人就笑了。她不说话，却把胡琴攥得更紧。
        ⑬多年后我常常回想起那个夜晚。我不知道那夜，那对盲人夫妻，都想了些什么。只希望，我那声稚嫩的喝彩，能够让他们在永远的黑暗中，感受到一丝丝的阳光。
        ⑭尽管，我承认，那并非我的初衷。
