[Intro]
E  Emaj7  Bsus4/Ab  A2 (2X)

[VERSE 1:]
         E            Emaj7
All the boys voices cracking
        Bsus/G#
Oh, the moaning half tones
A2              E      Emaj7        Bsus4/Ab   A2
Come summertime, we're all the same age       here
         E             Emaj7
All the tension and the terror
            Bsus4/Ab              A2
Thin-limbed gorgeous green eyes smiling
    E   Emaj7 Bsus4/Ab     A2
And I'm going straight to hell

[Channel]
Bsus4    Bsus4/A    Bsus4/Ab      Bsus4/A   Bsus4 Bsus4/A        Bsus4/Ab  Bsus4/A
All the possibility        and promise just weighs on me so heav----ily

[CHORUS]
E
And I try but I'm not convincing
C#m
Your lips, they pout and twist and
F#m                         A         B
I die trying just to keep myself from kissing you
E
You take in everything with 
B
a subtlety I envy
F#m                          A       B
It's somehow all I need just keep me guessing please

[Interlude]
E  Emaj7  Bsus4/Ab  A2 


         E            Emaj7             Bsus4/Ab        A2
Darling, all of these awkward jumpstart-stalling conversations
          E       Emaj7   Bsus4/Ab   A2
Mean much more to me than any-------thing
         E              Emaj7
It comes down to me and you
            Bsus4/Ab             A2
And whether we're supposed to or not, 
         E          Emaj7    Bsus4/Ab    A2
we still will we're so much  better     off than them

[CHORUS]


[BRIDGE]
C#m
A look, A laugh, A smile, A second 
A
passes by and I regret it
B          A      B
words just aren't right
C#m
Sometimes I just can't explain
A
All the ways you devastate me
B      A     B
Always on my mind

[CHORUS x2]
