My cat doesn't like what I gave him for breakfast, so he's going to pretend it's not there and cry at me all day as if he's STARVING.
Sometimes we do that in our writing. We know something needs to be fixed, but instead of facing the issue and solving the problem we ignore it. Maybe if we work on something else, it will go away by itself.
I have one story I've been working on for a long time. Well several, but one for the purpose of this argument. I have the second and third in the series done, and I think they're good. But the first needs some serious work. Eventually I'll just have to bite the bullet (which has an interesting origin--look it up) and start working on it, but right now I have a lot of other projects and I like the story just the way it is and I don't want to remove characters and i don't want to rewrite and and and... Every time I go back to it I fiddle, hoping that I can get around the inherent problems.
It never works. That pile of stinky cat-food just sits there, mocking me. It won't oblige me my turning into something else.
Maybe I think if I whine at someone enough they'll change it for me. :)
