What am I to you? (Norah Jones)

What am I to you?

Tell me darlin' true
To me you are the sea
Vast as you can be
And deep the shade of blue

When you're feelin' low
To whom else do you go?
I'd 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 givin' you the ball

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

If my sky should fall
Would you even call?
I've opened up my heart
I never wanna part
I'm givin' you the ball

When I look in your eyes
I can feel the butterflies
Could you find a love in me?
Would you gave me a tree?
Don't fill my heart with lies
I will love you when you're blue
But tell me darlin' true
What am I to you?
