VERSE 1
D           G               D             G
I have been thinking, which I shouldn't do 
         D          G           Em            A
Cause it gets me in trouble and farther from you
G
I don't want a sentimental          
G/D                                   D   G   D  G
Short and sweet and confidential Goodbye
D              G        D         G
My thoughts belong in a book in a store
              D        G         Em        A
Where they're silently read, but spoken no more
G                              G/D
I didn't give my all and to be honest with you
              D   G   D  G
I didn't even try

PreChorus
Em                         D/F#
Well I want you back so bad
           G/D
I'm gonna change the way I'm acting
           A                G     N.C.
I'm gonna change and I'm so glad

CHORUS
          D            G
I'm gonna write you a letter
D               G
So much for the better
D                 G
And if it goes my way
              Em              A
I'll have you running back to me
D                  G    
I'm a natural born forgetter
D               G
So much for the better
Em         D/F# 
I can be romantic
G/D           A 
I just got to try to be

VERSE
D                G       D            G 
I have been thinking, again this is bad
   D             G            Em              A    
It seems that my thinking can drive you quite mad
G                                       G/D
But you can't say there's another word, though
                           D       G   D  G
To call this feeling in my heart
Em                         D/F#
I admit I take advice from more romantic minds
          G/D                        A           G
But I can proudly reassure you this idea was all mine

N.C.      D            G
I'm gonna write you a letter
D               G
So much for the better
D                 G
And if it goes my way
Em                            A
I'll have you running back to me
D                     G
I'm a natural born forgetter
D               G
So much for the better
Em         D/F#
I can be romantic
G/D           A   
I just got to try to be

Em                         D/F#
I admit I take advice from more romantic minds
          G/D                        A
But I can proudly reassure you this idea was all mine


N.C.       D            G
I'm gonna write you a letter
D               G
So much for the better
D                 G
And if it goes my way
              Em              A
I'll have you running back to me


D                    G
I'm a natural born forgetter
D               G 
So much for the better
Em       D/F#
I can be romantic
G             A
I just got to try to be


Em          D/F#    G/D          A       D  G  D G
I can be romantic, I just got to try to be
Em          D/F#    G/D          A       D  G  D G  D D/G D
I can be romantic, I just got to try to be
