Vianne, one of the main characters, says this in one of her flashbacks. I connect with this quote so much, as should we all... what do we remember of our memories, or at least try to? Love. Even if we try to recall the hurt that we truly felt in a moment, we can conjure some of it to fruition, but it will never be as bold as that first sting; time diminishes the wound. We live and move on.
Vianne says this after talking about a troubled time in her life, and searching for love in the wrong places (I'm not placing a spoiler-alert here... you MUST read this book!).
