When a character introduces herself, sometimes it can be difficult for the writer to understand why this person is the way they are. We try to uncover her life, her background, her parents, whether or not she has a pet, what is her favorite color–and why is it her favorite color?
Environment can play a factor. When I realized who Bliss really is (spoiler deleted!) I knew that she would have been placed in with a foster mother so that she would have as normal and mundane a childhood as possible. A cottage in a distant shire, watched over by a woman of solid common sense like Mrs. Dalyrymple.
