Comparing Two Writings - Perks and Writing a Paper

When I sit down to write a three page paper, I am writing to show my teacher my knowledge of a subject. Usually, I try to sound sophisticated because it makes me feel as if it shows I know more than I do. While I know that is not true, it is the tone that I subconsciously set. There is a very clear format when I write a paper for a class. "Zeffireli’s differential choice of not having a crowd in the room detracts from any respect the King may receive and the respect the King has for Hamlet." My writing does not convey my real voice or tone. It almost as if I just know to follow a formula. When author's begin to write stories they adapt a different character for a different audience every time. Stephen Chobosky, the author of Perks of Being a Wallflower, adapted a character named Charlie. Charlie diaries and the reader gets to understand the story through the stories he tells his diary. Since he is only in 9th grade, Chobosky used vocabulary and diction to demonstrate his mindset.  While Charlie is shopping for Christmas presents for his family... "My mom likes old movies and plants. My dad only likes golf...and he doesn't play baseball anymore." The simplicity of the diction mirrors his young and simple thought process.  Chobosky is not trying to get an A or show anybody that he read a book. He is free to write in any style and in anyway. Changing the audience, changes the purpose and tone.
