D?
I saw you
                 D
At the grocery store
Oh You both looked happy
D?                D
Picking out the usual
She's a carbon copy
G                  Bb/H
Of everything you lost
                   A
Of everything I'm not
I guess you just forgot
How to pick 'em

If she's the one 
I've heard about
I'm disappointed
If she's the reason 
Why you left
I'm not impressed at all
Well 
This looks like the end
Yeah
We can still be friends
Congratulations

Refrain:
D   Bb/H      F
Let me be the first
    G
To wish you the worst
D           Bb/H
'Cause I think you
F             G 
Deserve each other
D   Bb/H    F
Let me the curse
That creeps 
G           Bb/H
Under your skin
            F
Until your heart 
Caves in
    G
And you wish 
        D
She was me again

And again 
And again 
And again

Well, someone had 
To tell the truth
and I'm always honest
I read you 
Like an open book
And it's obvious to me
She's just 
The one between
Heading no where fast
Sure 
It's gonna last forever

Let me be the first
to wish you the worst
'Cause I think you 
Deserve each other
Let me the curse
That creeps 
Under your skin
Until your heart 
Caves in
And you wish 
She was me

Let me be the first
To wish you the worst
'Cause I think you 
Deserve each other
Let me the curse
That creeps 
Under your skin
Until your heart 
Caves in
And you wish 
She was me again

And again 
And again 
And again

Oh, you wish 
You wish
You wish 
You do 


i think it's okay, really not perfect but okay=)
