I've just realised that most of what I've written over the last couple of days is tantamount to a deus ex machina, and it discharges the tension in the story in entirely the wrong place and in completely the wrong way.
I'm going to have to redo it. All of it. Even though quite a few people might not notice it, I would, and it would be a permanent reminder to me of how badly I can write if I don't put my mind to it.
What's particularly ironic about it is that it's one thing which particularly spoils other people's writing for me, and I'm horrified with myself that I could do something so awful.
Those of you who write: what particular structural or stylistic fault do you find most reprehensible in others' writing, and do you ever find it creeping into your work if you're not careful? How wretched does it make you feel if it does?
