Nine Inch Nails - This Hart's Not Made Of Stone lyrics

I know sometimes I'm hard I know sometimes I'm cruel I know sometimes I'm slow And often act the fool And though I think the world of you But I can't take it all my time I have lose control sometimes I've got to live my life You take me up, up, up To the top of the sky You bring me down again You always bring me down again But there's one thing you should know This heart's not made of stone There comes a time when you must go A time to let your feelings shows A time to tell the world just what you know And sometimes I must be alone But you know that you can telephone I know that you are stronger than you say But there's one thing I should know This heart's not made of stone
