What is integrity? I remember the Colombian gabriel Garcia marquez once said "keep one's word is a treasure, should not be arbitrarily squandering." We, too, can't do that thing, don't promise to others; Since said yes, you must do it. Remember once, the classmate ask me to go to the park to play, convention concentrated at the gate of the park, I readily agreed. But come on that day, I overslept because not careful, hurriedly get up, dress up to go out.

　　Even by the park gate, a personal cinema is not to see. "Oh! She won't wait too long to go home? Or go away? Whose question, I was in a hurry with a mood of walking up and down at the gate of the park. Or go home first, make a phone call to ask her. But at home, my mother is called me to do housework, forgot all about it.

　　By Monday morning, I walked with heavy steps back to the class. I promise, lost the most important thing in life is a treasure. Suddenly, a familiar voice from behind, it is her! She came over and said to me: "the day on Saturday, I waited for you for a long time, see you come, and have something urgent to go first." After I listen to, also illustrates the reason with her. Life such as song, or high or low, or sorrow, or joy, because good faith, it becomes sweet. Let everyone keep sincerity!

　　诚信是什么呢?我记得哥伦比亚的马尔克斯曾经说过“守信是一项财宝，不应该随意虚掷。”我们也是一样，办不到的事情，不要随意答应别人;既然答应了，就一定要办到。记得有一次，同学约我去公园玩，约定在公园门口集中，我爽快地答应了。可到了那一天，我因为不小心睡过头了，赶紧起床，打扮好出门了。

　　可到了公园门口，连一个人影都没有看见。“哎呀!她不会等太久，回家了呢?还是走开了呢?满头疑问的我带着着急的心情在公园门口走来走去的。还是先回家吧，打电话问问她。可回到家，妈妈就叫我去干家务了，忘了这回事。

　　到了星期一早上，我迈着沉重的步伐回到班上。这下我失信了，失去了人生中最重要的一笔财富。忽然，身后传来了一个熟悉的声音，原来是她啊!她走过来跟我说：“周六那天，我等了你好久，都不见你来，又有急事就先走了。”我听后，也跟她说明了理由。生活如歌，或高昂，或低沉，或悲戚，或欢快，因为诚信，它变得悦耳。让我们每个人都守诚信吧!
