There are two main classes of writers that can — broadly — be discerned by this bright line divider:
1. Those who know how to use and appropriately do use m-dashes.
2. Pseudoliterate imposters (whose “work” is usually edited by lobotomized Bonobo Chimpanzees).
Oh, there are many other indicators, but that one will generally do the trick.
YW.
There may be those among my (2?) readers who question which class I belong in based on my own use of an m-dash above. If so, nanny-nanny-boo-boo to you. *heh*
BTW, I read the occassional pseudoliterate imposter for the dubious pleasure of making snarky comments in notes, then reposting those notes in a Amazon review. Yeh, it’s kinda mean, but they EARNED it. One such pseudoliterate imposter I read recently described a wedding (it was in an “action hero” sort of seventh grade boys’ fantasy). My impression of the “classy” (so asserted by pseudoliterate imposter) wedding was of a kinda trashy “trailer park” wedding. (And yes, I know some perfectly nice folks also live in trailer parks, but I’m invoking the “TPTrash” meme for shorthand, here.) It was a hoot trashing that, since it had already trashed itself.
*heh* Your usage was fine. Heck, it was probably better than my own.
By the way, I’m firing my bonobos.
B-b-b-but Perri! They work so cheaply! *heh*
