Capo 4

Intro- Em  C9   C7#9

VERSE1:
   Em
The mirror's image,
 C9          C7#9 
   tells me it's home time,
Em
   But I'm not finished,
C9                C7#9
'Cause you're not by my side.
Em                                    C9   C7#9
And as I arrived I thought I saw you leaving, Carrying your shoes,
Em                                 C9   C7#9
Decided that once again I was just dreaming, Of bumping into you


CHORUS:
Em                    C9
Now it's three in the morning,
        C7#9
And I'm trying to change your mind,
Em                        C9
Left you multiple missed calls
          C7#9
And to my message you reply.
Em                                   C9   C7#9
   Why'd you only call me when you're high?
Em                                      C9   C7#9
High, Why'd you only call me when you're high?

VERSE 2: (no acoustic) tab played:


Somewhere darker,
Talking the same shite,
I need a partner,
Well are you out tonight?

Em                                  C9   C7#9
It's harder and harder to get you to listen, More I get through the gears,
Em                         C9   C7#9
incapable of making alright decisions, and having bad ideas.


CHORUS:
Em                    C9
Now it's three in the morning,
        C7#9
And I'm trying to change your mind,
Em                        C9
Left you multiple missed calls
          C7#
   Why'd you only call me when you're high?
Em                                      C9   C7#9
High, Why'd you only call me when you're high?    HEY

INSTRUMENTAL: (Riff but can play intro over the top)

OUTRO:
Em                    C9
Now it's three in the morning,
        C7#9
And I'm trying to change your mind,
Em                        C9
Left you multiple missed calls
          C7#9
And to my message you reply.
Em                                   C9   C7#9
   Why'd you only call me when you're high?
Em                                      C9   C7#9
High, Why'd you only call me when you're high
