It’s the blurt. This is the fun part of a new writing effort, when imagination spins up and the story rolls out like it’s on a fast-moving conveyor belt. Questions are asked about who and why, but answers are filled in fast. The story unwinds, teaching him what’s going on, and he spills it onto the page, connecting new dots, splicing in realized bits of stuffing about who these people are, why they’re together, their objectives and problems, their story.
He really doesn’t know where it’s going but that doesn’t matter. He’s writing, and it’s going somewhere. He’ll need to sweat some details later.
That’s later. Just enjoy the trip. Drink coffee and enjoy the trip.
