 With a first person narrative it is important to consider how the story is being told, i.e., is the character writing it down, telling it out loud, thinking it to themselves?And if they are writing it down, is it something meant to be read by the public, a private diary, or a story meant for one other person?The way the first person narrator is relating the story will affect the language used, the length of sentences, the tone of voice and many other things.
