How does a heart beat when it is missing?

Carved out and given away.

The wounds had hardly started healing

When you threw it away.

Tossed aside, meaning nothing

But at the time, you thought it was touching.

You'll pick up that heart again

One day

And I will stay at your side.

But what do I do in that time?

How do I live without a heart

When waiting is the hardest part?
