I don't normally post lyrics but this one is just too good.

What am I to you by Norah Jones:

What am I to you
Tell me darling true
To me you are the sea
Vast as you can be
And deep the shade of blue

When you're feeling low
To whom else do you go
See I cry if you hurt
I'd give you my last shirt
Because I love you so

Now if my sky should fall
Would you even call
I've opened up my heart
I never want to part
I'm giving you the ball

When I look in your eyes
I can feel the butterflies
I will love you when you're blue
But tell me darling true
What am I to you
