intro: capo 4th fret or basically what ever suits your singing

A, F#min, B#min, A for the intro

and then:

F#min           C#min
I know what you did
B#min      D (xx0232@1)I know 
F#min                  C#min
So I'ma let you taste hurt
B#min
I ain't washing my sins
DI (xx0232@1)ain't washing my sins
 
and pretty much for the rest of the song it goes

F#min, C#min, B#min, D

Now we're lying about the nights
Hiding it all behind the smiles
Take a look at what you did
You probably thought that you'd break my heart
You probably thought that you'd make me cry
But baby it's okay
I swear it's okay

'Cause I know everything
I know everything
I know everything
I know everything

Now these talks don't twist like they did before
It's hard to keep you up
And you are crying
But baby it don't hurt
Oh, like you thought it would 
The more of you the merrier

Now we're lying about the nights
Hiding it all behind the smiles
Take a look at what you did
You probably thought that you'd break my heart
You probably thought that you'd make me cry
But baby it's okay
I swear it's okay

'Cause I know everything
I know everything
I know everything
I know everything
