Memoirists enter into an agreement with readers: I will tell you an emotionally true story in a skillful way. I will make it worth your while. And while my memory is imperfect, I haven’t invented memories. I haven’t invented facts. If I compress timelines, combine characters or conflate events, I will tell you. The other people in my book would tell the story differently; this is my own, true version.
