    Em                   G
She puts her pen to paper
    Em                   G
Lines across their hearts
    Em                   G
You did it all to erase her
    Em                        G
You left her standing in the dark
    Em                   G
This time she’s praying for silence
    Em                   G
Hoping that you would understand
    Em                   G
She’s just building these roadworks
    Em                   G
So it’s clearer when they land
    Em          A        Bm
You can’t still own what you let go
    Em           A        G
What don’t you understand?
[CHORUS]
Bm                G                          D            A
Tough luck I said I’d be here in a month but you waited two
Bm                G                          D            A
Only coming back ‘round because you heard I was with someone new
Bm                           G
And I was waiting here till you came back
D                        A
My heart was bleeding black
Em                            Bm
It’s tough love that I’m giving you, 
Em                   Bm
it’s tough luck on you
He asked a question, she answers
He made a crossword spelling guilt
Empty boxes filled with chances
But you just can’t leave the rose to wilt
You can’t still own what you let go
What don’t you understand?
