I admire C. Hope Clark, author of the Carolina Slade Mystery series and publisher of Funds for Writers which I've subscribed to for years. Her blog posts are instructive and interesting. She has written a post on the word Self. I think you will gain some insight into all your selves when you read Hope's essay here.
So not only did you teach me about writing memoir, you also taught me about reading and thinking about how others write memoir. Thank you so much! Rebecca
