The first time that I saw you Looking like you did, We were young We were restless Just two clueless kids, But if I knew then What I know now I'd fall in love. You're on a bus in chicago Three rows to the left You know my heart Is reaching for you But we never even met If I knew then What I know now I'd fall in love. 'cause love only comes Once in a while And knocks on your door And throws you a smile And takes every breath, Leaves every scar, Speaks through your soul And sings to your heart But if I knew then What I know now I'd fall in love. On a summer night In august Backseat of my car Said I'm trying to get To know you, I took it way to far But if I knew then What I know now I'd fall in love. (wooaahh) 'cause love only comes Once in a while And knocks on your door And throws you a smile And takes every breath, Leaves every scar, Speaks through your soul And sings to your heart But if I knew then What I know now I'd fall in love. (woah) I used up A lot of chances But you give them back But if again It comes crawling Im gonna make it last.. 'cause love only comes Once in a while And knocks on your door And throws you a smile It takes every breath, Leaves every scar, Speaks through your soul And sings to your heart But if I knew then What I know now (woah) If I knew then What I know now I'd fall in love...
