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
