Who Am I?

Who am I? This reminds me of the question from the movie The Breakfast Club when the teacher for detention says the kids must write a 1,000 essay on who they think they are. Brian is clipping his pen on his lip saying "who am I, who do I think I am..." When John looks over at him and makes him uncomfortable. The 5 kids must write the essay on who they think they are, but by the end of the day, they realize that although they come from different backgrounds, really, inside they are all the same type of kids.
