The background girl

Sarah has lived in the background all her life. She sits in the back of the classroom, keeps to herself, and doesn't try to speak out. She is a observer. A deep thinker. She is incredibly talented, but doesn't let it show. But she has a notebook with some of her observations. The ones she thinks are the least important. Which makes them even more important to her, because they are like her. If they weren't there, everything seems like it would be the same. But everything effects something.
