Life should be like a game of cards You make a mistake Shuffle the deck and start over It should be just like driving in your car Get lost and your navigation system Gets you closer [Pre-chorus:] But there ain't no handbook You're on your own Got no instructions When it comes to love Cause once you do something Can't be undone Wish I could take back Letting you go [Chorus:] If I knew then What I know now I wouldn't have said I don't need you around Alone in this mess Silence is so loud So I would treat you the best Baby if I knew then What I know now (What I know now) What I know now (What I know now) What I know now (What I know now) Yeah I would treat you the best Baby if I knew then What I know now Life should come with remote controls Then I just rewind it to The time it was better It should have a restart bu*ton So, I could travel right back To the day that I met her [Pre-chorus] [Chorus] Cause there ain't no handbook You're on your own Got no instructions When it comes to love See once you do something Can't be undone Wish I could take back Letting you go [Chorus x2]
