If tomorrow brought someone you used to know Someone who hurt you a long time ago If he showed up at your door again What would you say to him? If he told you his whole world was coming apart If he said he was sorry and poured out his heart Could you open up your arms again? Would you let a fool come in? Now, he knows, he should never have left you And ever have done you so wrong But a fool never plans for tomorrow No, he don't miss a thing till it's gone If he told you with teardrops how lonely he's been If he promised to love you like you once loved him Could you open up your heart again? Would you let a fool come in? If I told you my whole world was coming apart If I said I was sorry and I poured out my heart Could you open up your arms again? Would you let a fool come in? Could you open up your heart again? Would you let this fool come in?
