A run-on sentence is actually two sentences stuck together with a comma or perhaps nothing at all, this is a shitty example but I hate writing exemplars and so this is what you get. #RunOnSentence

@GramrgednAngel I do those and sentence fragments all the time because I'm writing from a fixed perspective inside the head of one singular character (who dropped out of school when he was 13 but anyway).

I know they're grammatically incorrect, but they're correct for this one person's internal narrative describing the world.

Totally fine by me if people want to pass my work by because of technical no-nos. This ain't no SAT essay!

@pelielios Which makes them perfect for your work.

Context matters.

@GramrgednAngel I also get lax in, say, steamy scenes where the perspective is more fragmented and time is sort of elastic.

Nobody wants three pages of "in, out... in, out... oh finally, we're done here! Jeez, that was an ordeal."

@GramrgednAngel In thinking about it, there's kind of a literary version of pointilism.

You wouldn't necessarily use it in every scene unless that's your book's whole thing.

Yet there are times when brevity makes a lot of stylistic sense.
