Something was pointed out to me in my most recent writing that just about has me gagging on such an amateurish error. A simple naming of a character throws off an entire theme by establishing its own.
Eve–crabapple–naked–temptress. All in a story that obviously (too much so, to the point of contrived) screams Adam and Eve and yet this had nothing to do with the story. True, when the name Eve came up I found it vaguely was appropriate enough in a secondary way and yet never realized that what followed likely was a mental chain that overtook the story.
That’s why trusted readers are the best friend of the writer.
