Hey, Redskyfalling!
This is your local psycho, back from a brief trip to PIMD. Probably slipping back into retirement soon. So I'll be a little less snippy than usual.
Duing NaNoWriMo, you write. And when you hit a wall, you stop, and wait for a bit. And then you write some more. When it comes naturally to you, write it. It doesn't matter how stupid it sounds, you can fix it later. For all you know it's that little editor demon preying on your word count again. So yeah. Just be a geek and write like you mean it.
