We writers give our characters quirks and habits to make them relatable and different from one another. Fingernail chewing, smoking, polishing glasses, using certain expressions. The trouble is, it’s easy to forget about them while creating the plot.
Maybe it doesn’t matter. Once the reader has absorbed that this one mangles paper clips and that one wears polka-dots, are further mentions of those quirks really necessary?
I think they are. Real people keep doing things like that, and we want our characters to be real. And it’s just sloppy writing to forget details. Besides, some readers are incredibly fussy. I remember reading a library book in which a certain character had a cat. The cat didn’t play an important role in the plot, but it was mentioned several times. Toward the end of the book, there was a fire in that character’s house and quite a lot of action around putting it out, making sure no one was injured, etc. But the cat was not mentioned. I have to admit, I may never have realized that, had not a previous reader made a marginal note, “What about the cat? Stupid author!” Readers notice details, even trivial ones.
So another editing pass may be in order. Along with tracking down typos and patching plot holes, add a quirks checklist. Insert characters’ habits, tics, pet phrases, and oddities at intervals throughout the text. And make sure not to mix them up.
But don’t overdo it. Sprinkle, don’t shovel. Aim for a happy medium between “Hey, what happened to the polka-dot bowties?” and “Geez, if I see another mention of paperclip abuse, I’ll throw this book at the wall.”
Fellow writers, do you give your characters memorable quirks? Have you ever forgotten about them in the course of perfecting the plot, or attached a quirk to the wrong character? Or as a reader, been annoyed at an author who did that?
