Capo 2nd Fret!

Intro:
C G Em Bm x2

C G              Em  Bm
 Hello, hi, goodbye
C               G               Em Bm
 So i'm saying, hello, hi, goodbye
C        G              Em  Bm
 Saying, hello, hi, goodbye
C        G              Em  Bm
 Saying, hello, hi, goodbye
 Saying...
C G                   Em
 Imagine a future of you and me
  Bm             C
 Seems good and then you leave
 G                           Em
 The pain in this vision is killing me
   Bm                 C
 Reality is we will never be
 G                         Em
 I'm prone to a love travesty
           Bm                  C
 And this feels like another tragedy
          G           Em           Bm                  C
 And the truth really is we're too young to understand love's demands
      G                        Em
 Love express will take you up five flights
     Bm                    C
 And let you go then, crash,
   G                 Em
 No replying from the ash
               Bm                C
 We'll just be burning up after that
                G                   Em                 Bm     
             C
 I'll hate you, or, you'll hate me, or, I'll take you, or you'll break me, or
               G                        Em
 And now I'm scared, cause I've been there
                      Bm            C
 Stuck in this prison, No optimism

 C             G               Em
 And now it's hello, hi, goodbye
          Bm               C                   G              Em
 My heart has no room for love, so i'm saying, hello, hi, goodbye
          Bm           C           G              Em
 My heart fell so in love, saying, hello, hi goodbye
     Bm                  C
 Any other time, I'd be yours,
         G                Em
 Saying, hello, hi, goodbye
           Bm             C
 But that thing in me is gone.

            G                Em
 I know you wish somehow I could explain
 Bm             C
 I'm still numb from the pain
     G               Em
 And I don't want to know your name
 Bm                C
 Please get up and walk away
 G                    Em
 I don't wanna fall in love again
      Bm                     C
 Don't want to start anything that could end
 G                           Em
 I know you think you can get through to me
            Bm                C
 But I'm on lock in loves penitentiary,
   G                 Em
 I already know how this goes
      Bm                  C
 Laid down, broken, heart broke
                G                   Em                Bm      
            C
 I'll hate you, or, you'll hate me, or,I'll take you, or you'll break me, or
              G                       Em
 And now I'm scared, cause I've been there
                    Bm          C
 Stuck in this prison, No optimism

              G               Em
 And now it's hello, hi, goodbye
          Bm              C                    G              Em
 My heart has no room for love, so I'm saying, hello, hi goodbye
          Bm         C             G             Em
 My heart fell so in love, saying, hello, hi goodbye
     Bm                 C              G              Em
 Any other time, I'd be yours, saying, hello, hi goodbye
           Bm             C
 But that thing in me is gone.
