A heart to spare

If I had a heart to spare
I'd give it to you gladly
So you could break it
And cut it as deep as
You do to mine

If I had a heart to spare
I'd let you throw it away
So you could step on it
And smash it as badly as
You did to mine

If I had a heart to spare
I'd put it in your hands
So you could play with it
And fool it as coldly as
You did to mine

But I have only one heart
One heart of my own
And I can't give it to you
I can't let you do with it
Whatever you feel like

I have only one heart
One single lonely heart
And for the first time
I'm going to keep it
Right here with myself
