In "My Sister's Keeper" by Jodi Picoult, the author reflects on the painful memories left by the loss of a loved one. It emphasizes the struggle of holding onto grief while acknowledging the importance of continuing life. The passage suggests that even though the memories may feel overwhelming, the act of living itself can lead to healing over time.

The metaphor of life as a tide illustrates how, initially, it can seem like nothing changes in our emotional state. However, as time passes, the accumulation of experiences and the process of living can gradually wash away the pain. Ultimately, the message is one of hope and resilience, encouraging readers to embrace life despite their sorrow.
