VERSE 1:

A                         E
i think it's about time i tidied up in here

A                          E
i haven't seen my floor in over a year

F#m                       D                     A    E 
can't open my door thanks to my fear, i've held back

(strum muted strings)

A                                E
and i don't know what part of my heart goes where

A                             E
it's way too complicated, too hard to bear

F#m                        D

when i return all the love you ever gave to me

think i've come to the end of my tether with you
i didn't ever think these words would come through
there's not much else that you could, that i could take

just how to be
when i refuse all the love you ever gave to me

CHORUS:

OOOooh
oooOOOOOOh


F#m             D               A    E
i think it's a shame we're as we are

F#m             D                        A
