Em          G                D D4 D D4 D
Maybe the rain's holding off,
Em          G                   D D4 D D4 D (Ill just refer 
Surely it knows, we're down here                   to this as  
                                                  D riff now)

Em             G            D riff
Walking 'round barefoot lost
Em                                      
Pretty soon these clouds have got to clear
G              D        
I know it's a lot
G                   D       
Arousing thunder I only ask it to stop
G               D        
For a second so I could coax you to talk
  

  (There could be a very quick G in here, Im not sure)  

Em  ^  D riff

Em             G              D riff

        Em                        G                       D riff
Didn't know who you were and then I was one more passerby
             Em                      G                    D riff
You were the girl in the entryway, thats all that I knew but
          Em                              
You were still in school and I was insecure
G              D    
I know it's a lot
G                D                           
Arousing thunder I only ask it to stop
G               D                   
For a second so I could coax you to talk
      F#m      F#m F#m F#m    F#m  F#m   D riff  D riff 
About your dreams and orange soda tea leaves, tv,  more....more
(If you dont like all the changes above you can just strum the F#m 
the whole way though til 'more' but it doesn't sound as good)
Em               G              D riff
Looks like the rains holding off
Em              G           D riff
Might as well take this slow
         Em                            G                      D riff
You know sometimes when I hold you in silence I listen real close
Em                              
Then I hear you talking to my soul


G                       D  
Well I know it ain't half 
G                   D   
of this story I'm only meaning to ask
G                   D                        D riff  D riff D riff etc
