accidental

  　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．
