With a capo on five
Play the root note with your thumb and pluck other notes in the chord to rhythm of
the beat, there are a few added 7's thrown in and other notes, just listen to the
song and you'll pick them up.

Here's the link of the recording for triple J's "like a version" if you want to hear it, 
and see him play, or just want to watch it for fun.

Verse 1
 Am
Oh he treats me with respect

He says he loves me all the time
 C
He calls me 15 times a day

He likes to make sure that I'm fine
              Am
You know I've never met a man who's made me feel quite so secure
              C
He's not like all them other boys

They're all so dumb and immature

Bridge
                  Am
There's just one thing that's getting in the way
                 C
When we go up to bed you're just no good

It's such a shame
                  Am
I look into your eyes I want to get to know you
                        C
And then you make this noise and its apparent it's all over

Chorus
Dm
It's not fair
         F
And I think you're really mean
     C
I think you're really mean
     G
I think you're really mean
     Dm
Oh you're supposed to care
         F
But you never make me scream
      G
You never make me scream

Am Am Am Am

verse 2
 Am
Now I lie here in the wet patch

In the middle of the bed
              C
I'm feeling pretty damn hard done by

I spent ages giving head
            Am
But then I remember all the nice things that you ever said to me
           C
Maybe I'm just overreacting maybe you're the one for me

bridge
                 Am
There's just one thing that's getting in the way
                 C
When we go up to bed you're just no good

It's such a shame
                  Am
I look into your eyes I want to get to know you
                        C
And then you make this noise and it's apparent it's all over

chorus
 Dm
It's not fair
         F
And I think you're really mean
     C
I think you're really mean
     G
I think you're really mean
      Dm
Oh you're supposed to care
         F
But you never make me scream
      G
You never make me scream

   Dm
Oh it's not fair
          F
And it's really not ok
       C
It's really not ok
       G
It's really not ok
      Dm
Oh you're supposed to care
      F
But all you do is take
      G
Yeah all you do is take

Dm Am C G Dm Am C 
G (Bit unsure about this, just make it pretty)

chorus
       Dm
(ohhh)It's not fair
        F
And it's really really mean
     C
I think you're really mean
     G
I think you're really mean
     Dm
Oh you're supposed to care
     F
But you never make me scream
      G
You never make me scream

   Dm
Oh it's not fair
         F
And it's really not ok
    C
really not ok
    G
really not ok
      Dm
Oh you're supposed to care
      F
But all you do is take
      G
Yeah all you do is take

    Dm           C
And it's not fair
   Dm           C             This parts a bit hazy too,
And it's not fair             but whatever chords you put in
   Dm           C             that match somewhere in the chorus
It's not fair                 will work fine.

  Dm      Am
nope
