A writer of short stories could change the details of a story to make it recognizably realistic to a South American reader by adding elements based on a South American's reality.

South America is the part of the American continent that was colonized by the Portuguese and the Spanish. It is known by its abundant nature, its rich culture and friendly people. Elements from the languages spoken there and from the variety of cultural manifestations could be added to the story, such as musical references, popular parties, religious references, habits, and values. In order to do that, the writer would have to do some research on South America. The writer can gather information from books or from the internet. South America's people is composed mainly by Afro-descendants, Indigenous people and European immigrants. Having knowledge about that mixed population, added to the countries' specific histories and difficulties can make a difference when the writer intends to make his story recognizably realistic to a South American because his reader would be able to identify with the story.
