In narratives, the first person point of view is the type of point of view in which one or multiple characters that are part of the story tell the events that occur in it through their point of view and perspective. Because of this, this is the only point of view that uses the first-person pronouns "I" or "We" and the forms of these to narrate the events. This can be seen in the excerpt presented as the narrator or narrators state "this girl seemed to mean to us the country" and "My Antonia More than any other person we remembered" that uses the first person pronoun "we" or form of it such as "us" that shows the story is told from people that participate in it rather than an external narrator as in the case of third person point of view.
