The only thing that it believed was that one day its master would come back .Its life, just as the water ,was elapsing on the cyan stone platform year after the year .As a dog ,it had its own principlenever leave or quit no matter birth, age, illness or death.It lied down there, for ten years, changing into a landscape. For life or for death, however separated, we pledged our word. We held each others hands until we grow old together.生与死的距离，对于一条狗来生与死的距离，对于一条狗来说，它无法参透，它只相信，说，它无法参透，它只相信，他的主人会回来。他的主人会回来。它的生命如它的生命如一注流水，一点一点在车站的一注流水，一点一点在车站的青石台上年复一年地流逝。作青石台上年复一年地流逝。作为一只狗，它有它的原则，不为一只狗，它有它的原则，不离不弃，不论生老病死。它卧离不弃，不论生老病死。它卧在那里，十年，透彻成一种风在那里，十年，透彻成一种风景。景。死生契阔，与子成说。死生契阔，与子成说。14.15.
