Prose Favors Information, Poetry Favors Music

I wrote The Liars’ Club longhand in notebooks. Then I’d type them up. I rewrite a lot, even as I go along. I’m a compulsive rewriter. I have a poet’s sense of perfection. Prose always seems inadequate to me because every line isn’t a jewel. But it can’t be. Prose favors information; poetry favors music and form.
