Refactoring 3 : Expecting Things to Change

Did I ever tell you what the definition of insanity is? Insanity is
doing the exact same fucking thing over and over again expecting shit to
change. That. Is. Crazy. The first time somebody told me that, I dunno,
I thought they were bullshitting me. So, boom, I shot him. The thing
is... he was right. And then I started seeing, everywhere I looked,
everywhere I looked all these fucking pricks, everywhere I looked, doing
the exact same fucking thing. Over, and over, and over, and over again
thinking, "This time is gonna be different. No, no, no please... this
time is gonna be different." I'm sorry, I don't like the way... (punches
crate aside violently) ...you are looking at me. Okay, do you have a
fucking problem in your head? Do you think I am bullshitting you, do you
think I am lying? Fuck you! Okay? FUCK. YOU. (beat) It's okay, man. I'm
gonna chill, hermano. I'm gonna chill. The thing is... all right? The
thing is I killed you once already, and it's not like I am fucking
crazy. It's okay. (beat) It's like water under the bridge. Did I ever
tell you the definition of insanity?

Who gets it, gets it.
