Michael: Damn bro stop acting like such a stool!
Jacob: That's kinda offensive bro. My brother is disabled and what you have done is shown a side of you that I have never known. Goodbye Michael. We can be friends no longer. You were my first love but now all this love has turned to hate.
Michael: I... I felt the same!
Jacob: Shut the fuck up you goddamned stool!
