A Disposable Heart

You can give up my heart,
So it's really okay,
When you're tired and sick of me,
You can just throw it away.

My heart's disposable,
dump it after use,
Only once you can hold,
So be careful on what to choose.

My heart's not that important,
I don't care much,
Crush it if you must.

'Cause it's all thanks to you,
That i realized my genuine purpose.
