You really love to edit your posts, don't you?
I'm really scatterbrained whenever I have to put thought into written words for some reason. When I had to write essays in college I'd thing of a good sentence for once paragraph, write it. Think of another good sentence for a paragraph two or three paragraphs earlier. Then think of a whole new paragraph to add and put in a placeholder to remind me to come back...
It ends up being a jumbled mess of wrong sentence structures (I'd have started a sentence, then gone and added something to another sentence in that paragraph, then come back to the that first sentence but finish it off with a structure that completely disagrees with the first.)
It's even the same when I make a post, it'll be jumbled at first, then I'll make a pass at cleaning it up, then another pass and think it's fine for posting, then I see it in the thread and see all these little stupid things that annoy me that I just have to fix.
