Nano cloud

I was once your cloud,

The one that sheltered you from the sun,

And you were once my cloud,

The one that poured rain down, so I could live.

Always love this song, very subtle so many hidden meaning behind it. 

please excuse the father-son gimmick, they're not even related. i think it was used to dodge the real intention of the song.

Wish you are well
