Dialogues In An Autobiography
I think that to write an attractive autobiography you need dialogue, one that is accurate and lively. You want people that are reading the autobiography to practically feel the words resounding in their ears, even though they are reading them. Take the people to experience the autobiography as if they were watching a movie or as if they were hearing the tale from your own mouth.
Even though you might not remember your conversations perfectly they need to be as close as possible to the reality of what they were in the past. This is because they need to get a good idea of what you talked about or heard others talking about. Dialogues help tell the story, as a matter of fact many of them are stories, so it is better to include them in your autobiography. However, the writing style of the author does also influence the conversations between characters, whether they are detailed, a bit made up, or lively or not.
