Finding out what you are. Ghost – a vision of a deceased person who is believed to appear or become visible to the living in the form of a vague image. There have been many cases in reality where one sees the ghost of their deceased loved ones or encounters some sort of paranormal activity in their life. “Proof” by David Auburn plays with the “ghost story” in his play to represent Catherine’s identity, memory. Auburn’s “Proof” focuses on four main characters; Robert, Catherine, Hal and Claire. Robert, who is an esteemed mathematician, is the father of Catherine, who is only 25 years old. Hal is the romantic antagonist, more of a nerd, sometimes charming. He is very uncertain about Catherine's academic abilities. Hal discovers a notepad in a drawer with extensive calculations. He wrongly assumes that the work is that of Roberts. In reality, Catherine had written the mathematical proof. But no one would believe her. She is now fighting to prove that she was the one who wrote the proof. The play takes place on the back porch of a house in Chicago. It begins when Robert wakes Catherine at midnight and one in the morning, because it is Catherine's 25th birthday. They decide to celebrate Catherine's 25th birthday by drinking the champagne that was on the table behind Robert. They have the typical birthday conversation a normal father-daughter would have: talking about their past, their present, and their future. At this point, the audience knows that Robert is not alive. It is only a manifestation that Catherine experiences. Catherine does not know that her father is not alive. But she deals with it nonetheless. She has a conversation with him as if he were real. She keeps the father-daughter conversation real. Although Robert suffered from mental illness due to his math skills, Catherine is in the middle of a paper......and Catherine together in a scene. It's either Catherine and Robert talking alone, or Catherine and Hal alone. Hal and Robert are never together in any scene. This slightly hints to the audience that Robert is not alive. But he is only a manifestation throughout the play. Similarly, in Shyamalan's The Sixth Sense, we see a scene early in the film where Malcolm is shot by an old patient, but as the rest of the film unfolds, we assume that Malcolm is still alive. Malcolm is feared to have psychic powers (Ruined Endings) in the same way that Catherine allegedly possessed her father's illness. Later, when these two characters discover that they saw nothing but a hallucination, they realize it's time to make a move. continue with life. Catherine finally gives in to her sister's plan to move to New York. And Hal publishes the Proof as Catherine's work.
