In the story, the author likely employs a plot device such as a conflict or a challenge to enhance the narrative surrounding the two characters changing a tire. For instance, if the characters encounter difficulties, such as bad weather or a missing tool, this conflict serves to heighten tension and drama.
The effect of this plot device might be to illustrate the strength of their partnership or to develop their characters through teamwork and problem-solving. By overcoming these obstacles together, the characters may grow closer, revealing their personalities and deepening readers' investment in their relationship. Additionally, the resolution of the conflict—successfully changing the tire despite setbacks—can convey themes of resilience and collaboration, making the story more impactful and engaging for the audience.
