Part of this is that I learned French as a written language before English, and narrative and dialog have always been very different creatures to me. Dialog just needs to sound like people talk, and I can do that. Narrative needs its own flow, needs to be interspersed with enough dialog, needs to convey information and move plot along without getting mired in itself.
It’s the cadence of narrative that I’ve been working on, how quickly or slowly or trippingly different stories need to go. Re-ordering sentences in ways that do nothing to improve clarity is a new thing for me, but it’s been necessary in working on cadence.
Maddeningly, I’ve so far not found a way to work on cadence that doesn’t involve revision and paying attention. It’s almost like writing is something that requires effort.
