Am 
 Say you goin' out late

That you do when you're lonely 
                            C 
And you're all about the chase 
                                  G 
But you won't ever let me catch you 
                        D 
And I wish I was the same 
  
But I know I'm gonna let you 
Am 
Win again and when I do 
     C 
It's gonna hurt like Hell 
              G

You're so high on attention 
                 C 
Taking miles for inches 
                  G 
Leave me in the darkness 
                       D 
Never finish what we started
