    庄周家贫，故往贷粟于监河侯。监河侯曰：“诺。我将得邑金，将贷子三百金，可乎？”庄周忿然作色曰：“周昨来，有中道而呼者。周顾视车辙中，有鲋鱼焉。周问之曰：‘鲋鱼来！子何为者邪？’对曰：‘我，东海之波臣也，君岂有斗升之水而活我哉？’周曰：‘诺。我且南游吴越之王，激西江之水而迎子，可乎？’鲋鱼忿然作色曰：‘吾失我常与，我无所处。吾得斗升之水然活耳，君乃言此，曾不如早索我于枯鱼之肆！’”
（《庄子·外物》）

    It was a cold winter day. A woman drove up to the Rainbow Bridge tollbooth (收费站). “I'm paying for myself, and for the six cars behind me,” she said with a smile, handing over seven tickets. One after another, the next six drivers arriving at the tollbooth were informed, “Some lady up ahead already paid your fare.”

    It turned out that the woman, Natalie Smith, had read something on a friend's refrigerator: “Practice random(不经意的) kindness and senseless acts of beauty.” The phrase impressed her so much that she copied it down.

    Judy Foreman spotted the same phrase on a warehouse wall far away from home. When it stayed on her mind for days, she gave up and drove all the way back to copy it down. “I thought it was beautiful,” she said, explaining why she'd taken to writing it at the bottom of all her letters, “like a message from above.” Her husband, Frank, liked the phrase so much that he put it up on the classroom wall for his students, one of whom was the daughter of Alice Johnson, a local news reporter. Alice put it in the newspaper, admitting(承认) that though she liked it, she didn't know where it came from or what it really meant.

    Two days later, Alice got a call from Anne Herbert, a woman living in Marin. It was in a restaurant that Anne wrote the phrase down on a piece of paper, after turning it around in her mind for days.

    “Here's the idea,” Anne says. “Anything you think there should be more of, do it randomly.” Her fantasies include painting the classrooms of shabby(破败的) schools, leaving hot meals on kitchen tables in the poor part of town, and giving money secretly to a proud old lady. Anne says, “Kindness can build on itself as much as violence can.”

    The acts of random kindness spread. If you were one of those drivers who found your fare paid, who knows what you might have been inspired to do for someone else later. Like all great events, kindness begins slowly, with every single act. Let it be yours!
