You think you're such a cool kid
And everybody likes you
Know you think I'm stupid
Say you know more than I do
But what you'll never understand
Is I used to be such a fan
But now you're such a cool kid
It's like I don't even know you
Yeah

I'm gettin' really sick
Sick of how sorry sounds
Comin' right out your mouth, oh
Don't get too comfortable
'Cause I might not be there
Next time you turn around

So what would you do if I leave and don't come back?
I hope it breaks you in two (I hope it breaks you in two)
If I gave back all the pain that you put me through
What would you do?

(Hahaha)

I've always been a nice girl
I'm pretty understandin'
But you mess up my head, boy
And you're takin' me for granted
And you're probably gonna throw a fit (throw a fit)
When I call you out on all your shit (all your shit)
Yeah, I used to be a nice girl
I bet you wish it lasted
Oh

I'm getting really sick
Sick of how sorry sounds
Comin' right out your mouth (out your mouth), oh
Don't get too comfortable
'Cause I might not be there
Next time you turn around

So what would you do if I leave and don't come back?
I hope it breaks you in two (I hope it breaks you in two)
If I gave back all the pain that you put me through
What would you do?

We'll make plans and I won't show up
I won't listen, I'll interrupt
When your birthday comes, won't answer ya
'Cause so what? So what?
I'll go out and kiss your friends like
Oh, my God, get over it
Yeah, go get drunk so you forget I'm gone

What would you do if I leave and don't come back?
I hope it breaks you in two (breaks you in two)
If I gave back all the pain that you put me through
What would you do?

(Ooh)
What would you do?
(Ooh)
What would you do?
