Anna: Spare...? Am I really just the spare?

I’m not part of the town, not born to be queen
Just somebody hopelessly inbetween
She’s the scholar, athlete, poet
I’m the screw up, don’t I know it
But then who could ever compare?
Of course they’re gonna think I’m just the spare
Well I won’t care

So I’m the extra button on a coat
In case another one comes loose
But if I have to be a button
Why can't I be a button that’s of use? (oops!)
I may lack style and I may lack grace
And once in a while I might fall on my face
But this little button deserves a place in the sky
This button wants to fly

Wait,...
