It’s a typical pet peeve of editors and agents: Stories that begin with dialogue.
In the latest Glimmer Train bulletin, author Benjamin Percy explains why a dialogue opening is so often ineffective:
When a reader first picks up a story, they are like a coma patient—fluttering open their eyes in an unfamiliar world, wondering, where am I, when am I, who am I? The writer has an obligation to quickly and efficiently orient.
Which is why writers should avoid opening with dialogue. I know, I know—you can think of ten thousand awesome stories that do exactly that. I don’t like any of them.
