 *The choices of authentic characters
In this short story the author implicitly shows a few common stereotypes of black African American people through the character of Dave's parents. First, as we see that Dave's mother was narrated as such a controlling mother. She asked Dave to work diligently, return home on time and sometimes she was rude, saying that Dave was a kind of foolish, crazy and naive child. It's clear that through her dialogues with Dave, we were directed to believe that she was just like the stereotype of most black African American women: loud, aggressive, demanding, and rude.
Then, Dave's father was also another representation of the common stereotype of black African American men. People usually believe that black African American fathers are kind of deadbeat fathers. They are violent and uneducated. The same thing also goes in this short story, once it was narrated implicitly that Dave was really scared of his father, he didn't even dare to tell him back since his father seemed to have favour on disciplining his sons with violent power. As a result, Dave didn't even have the courage to ask his father's permit to buy a gun.
Therefore, it can be assumed that the author used regionalism which is common in realist works. Regionalism refers to storytelling style that includes language/dialect and the unique personality of an area. In this case, the author wrote this short story with real characters who speak in a way that reflects their region class, gender, age and race
 *The relatable story setting
From the story, we learn that Dave's family and his friends lived in a rural area (probably farming land) where they worked for white people (like Mr Hawkin) in plantations and fields. It proves that the author even considers the setting of the story as an important element to portray the authentic life atmosphere of black African American people at that time. As we all know, black African Americans used to live in farming lands where they had to work for the whites, even became their slaves.
In addition, it can be said that the author uses mimesis and verisimilitude. The concept of imitating real and authentic life experiences which includes detailed description of everyday life, dialogue that accurately reflects the speech patterns of theme and place, and the authentic characters in creating literary or art works.
