       A7
Cold afternoon
    A7/E    A7/F
I sleep in some
             A7
Back of the room
A7/E      A7/F
Avoid the sun
                    A7          A7/E  A7/F
You turned off the light and I lost a lung
                 A7
You called it a night
    A7/E   A7/F
You had me won

                 F             C
Who told you to leave me all alone?
                 G
Leave me in the dark
                  Am
Leave me in the cold
                  F                    C
Who told you to leave before I could show?
                 G                 Am
You half of the man you wanted to know

(palm muted)
              F
But I had to face your last goodbye
              G
But I had to face your last goodbye
                Am
The look on my face, my bloodshot eyes
               F
So who won the war
            G (strummed)
Deep down inside
         A7  A7/E  A7/F
I can't decide
         A7  A7/E  A7/F
I can't decide

(Continue Verse part)
Only the dark can feel my touch
No kind of remark could burn this much
Cause I'm as cold as December
And I won't surrender                      
Until you give me back my life

                F             C
Who told you to leave me all alone?
                 G
Leave me in the dark
                  Am
Leave me in the cold
                  F                    C
Who told you to leave before I could show?
                 G                 Am
You half of the man you wanted to know

(palm muted)
              F
But I had to face your last goodbye
              G
But I had to face your last goodbye
                Am
The look on my face, my bloodshot eyes
               F
So who won the war
            G   (strum)
Deep down inside
           Am  G  F
I can't decide
           Am  G  F
I can't decide

                 G
I can't see the sun in the morning
        Am
Please send me a warning
      F
Next time I go through this again

            Am
All out of luck
    G       F
All out of time
                 Am         G       F
Who would have thought I'd lose my mind
(I improvise here since it’s hard to hear exactly what they’re playing)
No I can't decide
           Am    G
I can't decide
