OPENING OF THOMAS PAIN

The opening is a little different for me. Something is strange in the opening of the play. It sounded like he is doing something menacing. But when the narrator started reading it sounded like he was being rude to the audience and shows that he does not care about his audience point of view, what they want and don't want, what they did and didn't do. He is being rude purposely to his audience and I want to understand why.
