Who am I? pt duex

The first unit of sociology is over and it was awesome. I learned what makes people the way they are and how to study them. Everything made perfect sense until I thought about one thing. Who am I and what really makes me me? And after thinking about it over and over, I still have absolutely no clue who I am. I know I'm sixteen, but time is irrelevant. I know their is a black president, but is he doing anything different then all the white presidents we had before for me? I live a normal suburban life, going with the flow and just letting life run its course. I learned all these things  for why people act the ways they do and I can study everyone but myself. What makes me different from taco man at the top of my page. What is even causing me to write all of this? I can ask all these questions, but I'm not really proving a point. Who am I? I'm a very confused boy.
