Life should be like a game of cards
You make a mistake
Then fold the deck and start over
It should be just like drivin 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
Cuz 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
Wish I get remote controls
Then I just rewind into
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
Cuz 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
Oh oh oh oh yeah
Cuz there ain't no handbook （handbook）
You're on your own （your own）
Got no instructions （instructions）
When it comes to love （to love）
See once you do something
Can't be undone （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 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
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
