Final answer:
The speaker incorporates discussion of thefts at wedding receptions to deeply engage the audience by providing vivid, detailed storytelling that shows rather than tells, and hence, makes the narrative more compelling and thought-provoking.
Step-by-step explanation:
The speaker's discussion of thefts at wedding receptions serves a distinct purpose within the context of a story or essay. By highlighting the criminal aspect of wedding crashing, the speaker isn't simply going for shock value or only trying to provide an accurate picture of reality, nor are they solely focused on proving the inaccuracy of a film. The discussion of thefts is a tactic to immerse the audience in the narrative and to utilize concrete, sensory details that differentiate the engaging act of 'showing' rather than 'telling'.
This storytelling technique helps build emotional resonance and allows the audience to experience the story firsthand, potentially raising questions about morality, humanity, or societal norms. The speaker's ultimate aim is to capture the audience's attention, provoke thought, and present a richer, more nuanced truth.
