This means:
* They are a character in the story: The narrator is participating in the events, experiencing them firsthand.
* Their perspective is limited: They only know what they've seen, heard, and experienced, and their understanding of the story is shaped by their own biases and knowledge.
* They often use "I" and "me": The use of first-person pronouns is a key characteristic of this type of narration.
Think of it like this: You're reading a diary entry or a letter, where the writer is telling you their own personal story from their own unique viewpoint.
