Answer:
The metaphor of "memory is an ocean and bobs on its surface" suggests that memories are like individual pieces floating on the surface of a larger, interconnected whole. In storytelling, memory plays a crucial role in shaping the narrative, as it is through memory that we are able to access past experiences and emotions that inform our understanding of the present.
Memories can be used to create vivid and engaging characters by providing insights into their past experiences, motivations, and behaviors. Memories can also be used to create a sense of nostalgia, longing, or loss, which can add depth and emotional resonance to a story.
Moreover, memory can also be used to structure a story, as it allows for the exploration of different timelines and perspectives, and can be used to create a sense of suspense, mystery, or revelation. Memory can also be used to create a sense of continuity between different events in a story, as memories can connect seemingly disparate elements and tie the narrative together.
Overall, memory plays a critical role in storytelling, allowing writers to create compelling characters, explore themes, and structure narratives in ways that engage and captivate their readers.
