Who do you think you are?

I know I can't take one more step towards you

Cause all that's waiting is regret

And don't you know I'm not your ghost anymore

You lost the love I loved the most

I learned to live half a life

And now you want me one more time

And who do you think you are

Running 'round leaving scars

Collecting your jar of hearts

And tearing love apart

You're gonna catch a cold

From the ice inside your soul

So don't come back for me

Who do you think you are?

-Christina Perri
