Who are you?

I am a daughter and a sister to my family. To my friends I'm a specimen in a huge ecosystem of teenagers. To my teachers I'm the middle left desk, sometimes middle right. To the people who walk past me I'm the resting grouch face with the big hair. To me I'm a blend of daughter, sister, learner, friend, who is having a lot of trouble genuinely answering the big who are you question. Maybe who I am next week can give a better answer.
