Intro:      Em Bm Am D Em C C D

            Em                 Bm   
I have seen peace, I have seen pain
Am                                D    
resting on the shoulders of your name
               Em 
do you see the truth
                  C  
through all their lies
                                     D  
do you see the world through troubled eyes



G                   Bm               Em    
and if you want to, talk about it anymore
                C    
lie here on the floor
G-D       C              G    
cry,on my shoulder, of a friend



            Em                 Bm
I have seen birth, I have seen death
Am                           D
lived to see a lovers final breath
              Em
do you see my guilt
              C
should I feel fine
                                 D
is the fire of hesitation burning bright



G                   Bm                  Em
and if you want to, talk about it once again
           C
on you i depend
     G-D          C                G
I'll cry, on your shoulder, your a friend


Dsus2                            B
you and i have lived through many things
     Em                 C
I'll hold on, to your heart
D                     G
I wouldn't cry for anything
     B
but don't go, tearing your life apart


                Em                 Am
I have seen    fear, I have seen   faith
Am                              D
seen the look of anger on your face
G                   Bm                   Em 
and if you want to, talk about what will be

cry, on my shoulder, I'm a friend
G                   Bm               Em
and if you want to, talk about it anymore
                C
lie here on the floor


G-D        C               G  
cry, on my shoulder, once again
G-D        C               G
