Verse 1:
E             C#m               D       A
  What do you think inside your head (I wanna know)
E              C#m                 D   A
  So you think that this could end up (breaking you)
         E                  C#m
And your life is a timebomb set to explode
    D                     A
You talk out your ass and everyone knows
    E                         C#m
For once you should listen or care what I think
   D              A
Or I'll be gone before you can blink

  E                 C#m
A world you created set to explode
    D                          A
You lie through your teeth and everyone knows
    E                            C#m
For once you should take what im willing to give
   D                        A
