Jane was just a girl in my class. I never knew much about her except for that she was strong. She
didn't talk many. Her hair was black and purple, and she worn black sports shoes and a black sweater,
even on summer. She was, in fact, rather attractively. She never seemed care what the rest of us thought
about her, like the rest of my classmate. I didn't really want to get closest to her. It was only when we did
their chemistry project together that I begin to understand why Jane dressed the way she did.
