Throughout the casting episode of Project Runway you see many different kinds of people. All kinds of different personalities, views, raising, sexuality, and genders. Not everyone is the same, they may be similar but not the same.
While you write you create your characters or describe a person’s identity. You may write out directly what the person’s identity is or you may just put in little hints to what they are like. Writing a character’s identity could also be a way of expressing your own identity instead of saying it out right.
