Every fast-food employee knows that the drive-through window is the worst position. The window sticks with constant ice; the roar of engines hurts your 1; your words are lost in the howling wind.

    On a 2 afternoon, everything changed.

    Every once in a while, the sub-zero temperatures seal a 3 windows shut. Drivers don't exactly enjoy having to stand outside in the cold, 4 their orders into a speaker box, when they expect to drive through on their heated leather seats. In such cases, most customers tend to show their annoyance to the employees.

    This woman was 5.

    “I'll get the next car's 6 as well,” she said as she came up to the window to pay. She stood outside, 7 much snow on her hair. Though she was obviously freezing, her bright 8 lit up her face like a fire.

    “You can't 9 their drinks,” I said, confused and tired.

    “No, but I'll buy them,” she said. “Pay it forward and all that.”

    Completely puzzled, I charged her as 10, and when the next customer arrived at the window I explained what had just happened. I watched as his 11 changed — first angry to be out in the cold, then 12 at the random act of kindness, and finally, delighted by his 13.

    “I suppose I'll pay for the next order then,” he replied, nodding and waving at the impatient driver 14 him. He 15 over the cash and received his pre-paid hot drink. The trend continued. Customers arrived annoyed, only to leave 16 and pleased. Some were shocked to spend much more than they had expected, 17 others ended up receiving their order for less than half the price.

    Five vehicles passed, then ten, then twenty. No one refused to pay. Customers stood at my window 18 a fist-full of change to buy drinks for a complete stranger. Cars drove off, honking (鸣笛) and 19 their thanks.

    It only takes one customer, one person, to change the entire 20 of traffic. It only takes one moment, one smile, to warm up even the coldest of days.

    ①秋天到了，东北的街头小巷有两样东西格外多，一是密密麻麻的“花大姐”，在墙上埋头织着一张巨大的花毯，在阳光的余温里苟活；二是卖白菜萝卜和土豆的人，精气神儿倍儿足，吆喝声此起彼伏，把日子搅合出许多热闹的光景来。

    ②因为可以选择，所以每次买白菜我都要进行一番比较，挑品相好的、个头大的、硬实的，这样的白菜心儿抱得紧，好吃，也放得住，可以吃得时间久一些。我会趁着卖菜人不注意的当口，就势抖落几片白菜帮儿，至少可以掉几块钱的秤。

    ③精打细算总是好的，那是帮你看管好日子的一条忠犬。

    ④也有例外，有一对卖白菜的中年夫妇就蔫吧着蹲守在角落里，男人低头抽着闷烟，女人也不吆喝。两个人又黑又瘦、无精打采的，看不到一点儿生气。问其缘由，是不允许他们在卖菜的地段卖菜。城里的禁区太多，条条框框也多，他们就像晕头转向的羊，不知道哪里可以站立，哪里可以坐下。一颗热切的心被泼了冷水，就像饱满的白菜没来得及收割，早早就遇了霜寒。

    ⑤我劝着他们，“看，你们家的白菜多好，每一颗白菜心儿都抱得那么紧。一会儿就能卖完。”

    ⑥许是受了我的鼓励，那蹲着的男人站了起来，掐灭手上的烟，直了直腰。

    ⑦我注意到那个女人，自始至终没离开那些白菜半步，时不时地给它们盖盖被子，好像照顾着自己的婴儿，怕它们着了凉似的。这样的举动很让人不理解，天气还没冷到那种程度，即便是很冷，白菜们也不至于那么娇贵，它们差不多是蔬菜里最朴实的一种了。

    ⑧但是那一刻，我理解了。

    ⑨前几天刚刚看到一则简短的新闻：一个骑三轮车卖白菜的妇人被一辆轿车撞飞数米，落地后爬起来淡定地捡菜。这个短新闻的重点在于“淡定”二字，这出乎很多人的预料，因为在生命还没有确保无虞的情况下，一颗白菜竟然还受到如此“重视”！

    ⑩那么多的不解，是因为我们没有走进一颗白菜的心里。

    ⑪廉价的白菜，别说一车，就是几十车也比不得她狠狠地索要一笔赔偿吧。可是她的生活里，一直以来就只有白菜，她常年卖白菜，靠这个营生养活了自己和家人，所以，在她的生命里，白菜这个再平凡不过的事物是和她相依为命的。

    ⑫别人不懂一颗白菜的重要性，而对于她来说，白菜对她是有恩情的。

    ⑬收割白菜的季节，精神饱满的白菜最早被运走，赶个好价钱。最后剩下的白菜，人们称之为“扒拉棵子”。没抱成心儿，单薄得像没长成的少女，畸瘦、平胸，没有一点女人的神采。它们中有一些被主人收回家放到大缸里腌了酸菜，另外一些实在不入眼的，只好在大地里度过寒冬了，等待着牛羊们来啃噬。可是不久之后，剧情就发生了变化，城里人喜欢上了冻白菜的口味，把冻白菜用开水焯一下，炸点儿肉末酱，蘸着吃，味道极好。这下，大地上楚楚可怜的“剩女”们又一次得到了大批量待嫁的好机遇，纷纷走进城里人温暖的厨房。

    ⑭卑微的人就如同这白菜，饱满的、扒拉的，都在广阔的大地里繁衍生息。被栽种、被收获或者被冷落，一茬又一茬。

    ⑮卑微的人没有见过巨款，没有坐过飞机和高铁，他们眼里，更多的是零钱，靠着一颗颗白菜，他们的零钱也可以攒成很多张大额钞票，但转眼就汇去了很远的另外的城市，那里的冬天不冷，四季常青，那是他们的孩子上学的地方。

    ⑯我决定过冬的白菜都在这儿买了。我很小心地搬动一颗颗白菜，轻拿轻放，不会再轻易抖落一片白菜帮儿。我知道，于我，那只是可以让我少付几块钱的白菜帮儿，可是对于那卖白菜的人，那掉落的白菜帮儿是会喊疼的。
