what i am to you?

What am I to you???
Yeah well if my sky should fall
Would you even call
Opened up my heart
Never wanna part
I’m giving you the ball
When I look in your eyes
I can feel the butterflies
Could you find a love in me
Could you carve me in a tree
Don’t fill my heart with lies
I will you love when you’re blue
Tell me darlin’ true
What am I to you???
