Are you gonna curse?

Are you gonna cry?

Are you gonna air your dirty laundry

On a saturday night?

Are you gonna call your friends, sing karaoke?

Gonna sit at home all sad and lonely?

Lookin' like hell, 'cause your mascara's runnin', yeah?

Are you gonna cut your hair and dye it blonde?

Turn off your phone, turn up the song

Look in the mirror and feel like your nothing?

You think you know

You think you know

You think you know who you are

In somebody's arms

But you don't know

No, you don't know

Yeah, you don't know who you are

'til somebody breaks your heart.

Ha-ha-ha-ha-heart

'til somebody breaks your heart

Ha-ha-ha-ha-heart.

Are you gonna get mad?

Are you gonna get even, yeah?

Or are you gonna find

Something bigger than you to believe in?

Are you gonna stuff your face inside a pillow?

Gonna hang your head outside a window?

Feel a brand new day kissing your cheek

It's okay if you wanna hit rock bottom

Slip once or twice and call him

All I know is if you're anything like me.

You think you know

You think you know

You think you know who you are

In somebody's arms

But you don't know

No, you don't know

Yeah, you don't know who you are

'til somebody breaks your heart.

Ha-ha-ha-ha-heart

'til somebody breaks your heart

Ha-ha-ha-ha-heart.

'til somebody breaks your heart

Yeah, yeah

You can wave it like a flag

Or a scarlet letter

It make you bitter

Or make you better.

You think you know

You think you know

You think you know who you are

In somebody's arms

But you don't know.

No, you don't know

Yeah, you don't know who you are

'til somebody breaks

You think you know

You think you know

You think you know who you are

In sombody's arms

But you don't know.

No, you don't know

Yeah, you don't know who you are

'til somebody breaks your heart.

Ha-ha-ha-ha-heart

'til somebody breaks your heart

Ha-ha-ha-ha-heart.
