The cd player in the taxi was playing this chinese song over and over again...

"人有悲欢离合;

月有阴晴圆缺"

(loosely translated: the man has sorrow, happiness, separation and reunion; the moon may be cloudy, clear, full or cresent)

I wonder if he's feeling the emotion of the song, which hints at the sense of loss brought about by tides of change.

The moment was poignant and eerily real...

As though sensing my thoughts, he clicked forward and move on...
