                                                                                                            夏阳
    ①幸福路作为一条商业步行街，每天人流密集，左边有一条非常不起眼的小岔路，叫平安街，顺着平安街进去百余米，一拐弯，眼前生出一条南北向小巷，便是杭州巷。
    ②杭州巷狭窄细长，仅容得下两人并行，麻石板铺就的巷道，伴随着墙脚一线湿湿的青苔，一直延伸到尽头。巷子两边的建筑，古朴、荒凉，被圈在高高的院墙内。透过门缝，可隐约窥见一些雕梁画栋，当然还有断壁残垣。小巷里，渺无人烟，只有寂寞的风，顺着寂寞的巷道穿过，轻轻吹拂着墙头几株寂寞的茅草。步行在小巷里，抬眼望去，四周就像一幅油画，挂在墙上沉睡不醒。
    ③我此行的目的地是杭州巷10号，那也是整个小巷唯一的住户。我去的时候，正值深秋，碧空如镜。上午的阳光嫩黄羞怯，在墙头瓦瓴上探头探脑，却无法照进小巷。行走在小巷里，头上是一片金灿灿的阳光，人却站在岁月的阴凉中。驻足10号门前，我感慨颇多，犹豫良久，那两扇厚重的木门还是被我轻轻地叩响了。
    ④须臾，一个老太太站在门口。她的目光和善，完全没有都市人惯有的那种警惕。我结结巴巴地说自己是摄影发烧友，爱好用镜头来捕捉历史。老太太把我迎进院内。院子很大，里面种了不少花草。秋天的菊花开得正艳，五彩缤纷，白如雪，粉似霞，而黄的，则黄得热闹，亦黄得伤感。院内飞檐斗角，回廊石阶，曲径通幽。难以置信，在现代都市林立的高楼大厦脚下，竟然藏着这样的深居大院。
    ⑤老太太精神矍铄，红光满面，笑声爽朗，她说自己有八十高龄，有个留学海外的儿子，如果现在还活着的话，明年也将花甲之年了……老太太说她姓李，从十八岁结婚那年起，已经在这院子里生活了六十多年。六十多年里，女儿夭折，儿子客死他乡，佣人被遣散，老伴过世，一个个亲人相继离去，昔日门庭喧闹的大宅子里，最后只剩下她一个孤老婆子了。老太太说这话时表情恬淡，似乎是在谈论别人家的事情，看不出有任何的悲伤。
    ⑥我问：“这巷子为何叫杭州巷，和杭州有什么历史渊源吗?”
    ⑦老太太说：“现在知道这巷子来历的人应该不多了。说来话长，早在清朝末年，有一批杭商集体迁移来此，他们开茶庄、丝绸店和当铺等。买卖做大了，赚钱了，在这里扎根，抱团买地置业，于是就有了这杭州巷。你可别小看这巷子，它可是当年这座城市的心窝窝呢。巷道之所以修得这么窄，就是为了减少闲杂人员的进入。无论多大的官来访，文官落轿，武官下马，就是皇帝来了，也得老老实实从巷子口步行进来。”说到这里，老太太得意地笑了。
    ⑧我吃了一惊，没想到杭州巷在当年是如此的尊贵显赫。望着老太太一脸甜蜜而略带羞涩的回忆神情，我依稀看到了当年一个情窦初开的妙龄女子，被浩大的迎亲队伍捧进了这杭州巷。
    ⑨在杭州巷10号，如置身于山野的一处宅院里，都市的喧嚣和车流的嘈杂似乎远去。空气里，有花的阵阵清香，在明朗的阳光下，微微发酵。和老太太坐在一块儿喝茶聊天，真是一种享受，仿佛在翻阅一本厚厚的历史书。
    ⑩我拍了几张照片后，告别老太太，告别杭州巷10号，重新回到巷子里。我默默退出杭州巷时，一个磨刀师傅正挑着担子站在巷子口，高声叫喊着：“磨剪子嘞，戗菜刀!”他抑扬顿挫的叫喊声跌落在小巷里，溅起一巷子清脆的回音。磨刀师傅喊了数声，站了片刻，却没有走进小巷。
    ⑪我回到单位。主任问我：“老太太同意拆迁了?”我默默地望着主任难看的脸色。他的身后，悬挂着这座城市的规划蓝图，上面一条条粗大笔直的线路，纵横交错，气势凌厉。
    ⑫我向主任建议道：“按照老太太目前的身体状况，是很难熬过这个冬天的。要不，我们等到明年开春再说，如何?”
    ⑬主任沉默不语。

    You're out to dinner. The food is delicious and the service is fine. You decide to leave a big fat tip. Why? The answer may not be as simple as you think.

    Tipping, psychologists have found, is not just about service. Instead, studies have shown that tipping can be affected by psychological reactions to a series of different factors from the waiter's choice of words, to how they carry themselves while taking orders, to the bill's total. Even how much waiters remind customers of themselves can determine how much change they pocket by the end of the night.

    “Studies before have shown that mimicry(模仿) brings into positive feelings for the mimicker,” wrote Rick van Baaren, a social psychology professor. “These studies show that people who are being mimicked become more generous toward the person who mimics them.”

    So Rick van Baaren divided 59 waiters into two groups. He requested that half serve with a phrase such as. “ Coming up !” Those in the other hall were instructed to repeat the orders and preferences back to the customers. Rick van Baaren then compared their take-home pay. 'The results were clear—it pays to mimic your customer. The copycat(模仿者) waiters earned almost double the amount of tips to the other group.

    Leonard Green and Joel Myerson, psychologists at Washington University in St. Louis, found the generosity of a tipper maybe limited by his bill. After research on the 1,000 tips left for waiters, cabdrivers, hair stylists, they found tip percentages in these three areas dropped as customers' bills went up. In fact, tip percentages appear to plateau(稳定期) when bills topped $100 and a bill for $200 made the worker gain no bigger percentage tip than a bill for $100.

    “That's also a point of tipping,” Green says. “You have to give a little extra to the cabdriver for being there to pick you up and something to the waiter for being there to serve you. If they weren't there, you'd never get any service. So part of the idea of a tip is for just being there.”
