Looking back and picking up the pieces, if you will.
Right now, I am starting to piece together my story. I still plan to tell the story from three different perspectives: Margaret's, her husband's, and a removed third party. This is so that the story is as clear as possible to the reader (especially with the third party perspective).
I think I have a good footing on what I have, aside from the questions presented in my project plans. I have a third of my second draft ready (I did the hardest part first, Margaret's point of view, and plan to add some more subtle details to truly show her degression--memory lapses, difficulty in concentration and in multi-tasking, depression, and sadness (personality change)), and I have to still present the husband's and the third party's perspective, both of which are not afflicted by dementia. I have cut down on some of the ideas that I have, like some of you suggested, which takes a bit of the burden off. I'm not going to focus on race and race relations so much as the personal struggles Margaret and her family deals with in conjunction with her rape and prior drug use.
Feel free to comment on what I have presented so far, in either this reflection or in my plans.
