Okay, I know this will sound strange, but it annoys me when someone quotes a character from a work of fiction instead of the writer. I should let it go, I know, but I think it comes from my belief that writers are under appreciated in general.
It happens often enough in fiction. I mean, I can understand it to a certain point. People are probably more familiar with the character than the faceless writer. For example, if someone quotes a line from a Sherlock Holmes story, it’s usually attributed to Holmes and not the author, Sir Author Conan Doyle. Elementary, my dear Watson. 
But I think it’s even more prevalent in television and film. How often do you hear someone quote a line from, say, Casablanca (“Here’s lookin’ at you, kid”) or The Terminator (“I’ll be back”) and attribute it to the character or the actor? Happens all the time.
As a writer, I find it annoying. I mean, after I’ve spent time and effort to write a great story I would prefer to be the one credited with a memorable line. That came out of my head, from my imagination. I feel like it’s only fair.
And, full disclosure, I’m guilty of it, as well. I figured I should own up before someone goes back through my old posts and highlights every instance where I quoted a character. I’m sure there are more than a handful.
My partner has tried to help. After telling me to get over it – repeatedly – she’ll then suggest I try looking at it from another perspective. Writers want to be read, and as long as people are reading my stories, why should I care if they quote me or one of my characters? The character came from my head, as well, so if they get the credit, I sort of get it, too.
She’s right, of course. You can quote me on that.
