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
