Here's what we learn in the exposition:
* The Setting: The story takes place at a border crossing between Canada and the United States, where a Native American woman and her daughter are attempting to cross into Canada. This immediately establishes the setting of cultural and political tension.
* The Characters: We are introduced to the mother, who is unnamed, and her daughter, who is identified as "Laetitia." Their relationship and personalities are hinted at, but not fully revealed. The border guard, also unnamed, is presented as a figure of authority, though his motivations and personal biases are not immediately clear.
* The Conflict: The conflict emerges through the initial questioning of the mother and daughter by the border guard. We learn that they are considered "illegal aliens" by the guard, as they are not carrying proper identification. This conflict revolves around the mother's insistence on her right to cross the border, despite the lack of official documents.
* The Underlying Themes: The exposition also hints at the broader themes of identity, belonging, and the complexities of national borders. The ambiguity of the mother's status as an "Indian" is established early on, suggesting that she may not fit neatly into the categories defined by the border guard.
In short, the exposition in "Borders" is a slow burn, gradually building tension and leaving the reader with many questions. It is through this gradual revelation that the story effectively explores the nuances of identity, power, and the arbitrary nature of national boundaries.
