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

But there ain't no handbook; you're on your own
Got no instructions when it comes to love
Coz once you do something can't be undone
Wish I could take back letting you go

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 could rewind it to the time it was better
It should have a restart button so
I could travel right back to the day that I met her

But there ain't no handbook; you're on your own
Got no instructions when it comes to love
Coz once you do something can't be undone
Wish I could take back letting you go

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

Coz 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

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

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
