What Would You Do?

Think you're such a cool kid
Everybody likes you
Now you think I'm stupid
Say you know more than I do
But what you 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
I'm 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
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?
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'll 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, what would you do?
Ooh ooh, what would you do?
