My secret friend
I'll take you to the river
My secret friend
We can swim forever

In your skin
To die a little death
This time there's no code word
When everyday frays in hollow ends
Dream sweet love submersive

My secret friend
Oh take me to the river
My secret friend
We can swim forever

Break my deepest promise...
