Xu Zhimo - Chance

I am a cloud in the sky,
A chance shadow on the wave of your heart.
Don't be surprised,
Or too elated;
In an instant I shall vanish without trace.

We meet on the sea of dark night,
You on your way, I on mine.
Remember if you will,
Or, better still, forget
The light exchanged in this encounter.
