Answer:
The story "Mami and Papi". has many elements that prove that it is a personal narrative, some of those elements are:
*The use of the first person during the story.
*The character descriptions from the point of view of the narrator.
*The use of dialogue to develop the story
Explanation:
The use of the first person in any of its variants is a clear element of personal narrative since this kind of writing follows the events as the narrator, who happens to be the author, lived them. As the events occur the narrator/author includes their dialogues with the characters as they resemble them as they help to describe the characters in the story.
