Doesn't matter whos to blame  The bottom lines the same  And I am here alone with a broken heart    And I can't keep the tears  That I held back for years  Fallin from my eyes once they start    They say in time  Somewhere down the line  I will find someone to take your place    And though I hope that's true  So I'll get over you  Right now I question everything they say    Who are they  How do they know  What it's like ot love you  Then wind up all alone  Who are they  How do they know  They make it sound so easy  Take my heart then go  Who are they  And how do they know    I guess those promises we made  Were just something nice to say  And forever doesn't last that long these days    So how can my heart trust  After what happen to us  How can they say I'm gonna be okay    Who are they  How do they know  What it's like to love you  Then wind up all alone  Who are they  How do they know  They make it sound so easy  Take my heart then go  Who are they  And how do they know    Who are they  And how do they know
