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 getting really sick
Sick of how sorry sounds
Coming 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
If I gave back all the pain
that you put me through
What would you do?

I`ve always been a nice girl
And pretty understanding
But you mess up my head boy
And you`re taking me for granted
And you`re probably gonna throw a fit
When I call you out on 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
Coming 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
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
If I gave back all the pain
that you put me through
What would you do?
Ooh-ooh-ooh, what would you do?
Ooh-ooh-ooh, what would you do?
