In the novel I'm writing, I needed to include information about the death of the main character's mother. At first I included it in a transition piece (where time had passed and this was one of the things that had happened). So I created a 3-line "story" and cleverly connected it to the fact that the protagonist's child looked like the mother and the complications of that resemblance. And I was quite pleased with how it turned out.
But the event wouldn't go away. It kept returning in my consciousness, nagging at me for attention. The event itself and its circumstances weren't changing but I knew I had to make a bigger deal of Lola finding out and really put her in her reactions. I didn't analyze this. I just let it keep percolating and then it led me to a different beginning for the chapter, one that was more original and helped me show more things than just a few lines of telling it would have. I found a way to work in the scene of her learning and how she deals with it and what it says about her ability in relationships.
And then this afternoon, as I sat down to write this blog, a whole other importance fell into place and it was such a "Duh!" moment. This book centers on the difficulty of mothers and daughters. No wonder my psyche was nagging at me to make this piece a bigger deal. Glad I listened.
