[Verse 1]
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

[Pre-Chorus]
I'm getting really sick, sick of how "sorry" sounds
Coming right out your mouth, oh-oh
Don't get too comfortable
'Cause I might not be there
Next time you turn around, so

[Chorus]
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 (Ooh, ooh-ooh, ooh, ooh)
What would you do?

[Verse 2]
(Ha-ha-ha)
I've always been a nice girl, I'm pretty understanding
But you mess up my head, boy, and you're taking mе 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)
Yеah, I used to be a nice girl
I bet you wish it lasted, oh
[Pre-Chorus]
I'm getting really sick, sick of how "sorry" sounds
Coming right out your mouth (Out your mouth), oh-oh (Oh-oh)
Don't get too comfortable
'Cause I might not be there
Next time you turn around, so

[Chorus]
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 (Ooh, ooh-ooh, ooh, ooh)
What would you do?

[Bridge]
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

[Chorus]
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 (Ooh, ooh-ooh, ooh, ooh)
What would you do?
[Outro]
(Ooh, ooh-ooh, ooh, ooh)
What would you do?
(Ooh, ooh-ooh, ooh, ooh)
What would you do?
