I am a card-carrying member of the Anne Lamott fan club.
No question about it.
I have been insanely intimate with her books: Traveling Mercies, Bird By Bird, Plan B, and Rosie, among others. The margins are filled with notes, the words are underlined and re-underlined. I, like so many others, are convinced that Lamott wrote a particular book just for the reader.
Something Lamott said rings true for all writers, and especially for lawyers who write their opening statement or closing argument but so rarely read what they've written aloud. There's a big difference hearing with the ear:
"Nothing can break the mood of a piece of writing like bad dialogue. My students are miserable when they are reading an otherwise terrific story to the class and then hit a patch of dialogue that is so purple and expositional that it reads like something from a childhood play by the Gabor sisters. ... I can see the surprise on my students' faces, because the dialogue looked okay on paper, yet now it sounds as if it were poorly translated from their native Hindi."
TIP: Any time you have something to say aloud, speak out loud what you've written to hear how it sounds before you have to stand and deliver your words to the decision-maker or listener.
