The correct answer to this open question is the following.
"The Rockpile," by James Baldwin, reflects the idea that society is made up of insiders and outsiders. The character in the story that is an outsider is John.
This story written by Baldwin in 1965 appears in the collection called "Going to Meet the Man." The "Rockpile" refers to the story of two boys that are not allowed to go play in the Rockpile. All other boys in the area can go play at this site, except John and Roy. Roy decided to go anyway, without permission, and tells John to keep quiet. But as bad things happen in these cases, Roy got hurt because he is involved in a fight with other boys. When he gets home bleeding, his father gets angry with John -his stepson- as the father has always preferred his biological son, Roy.
