For one--let's be honest here--it's an excuse for candy. LOTS.
Husband and I cuddled up on the couch next to her to watch our once-a-year Halloween movies, several of which include Tim Curry. At least there was candy.
Probably the most important part of Halloween for me is that Halloween is actually TWO holidays. It is like a holiday in COSTUME.
To a great deal of writerly folks, Halloween is ACTUALLY Nanowrimo Eve.
If you don't know what Nanowrimo is, go here.
I have attempted and completed the Nano challenge every year since 2007. I might have written 50,000 words of various novels in each of those years, but it was not easy. Not at ALL.
Most years, I have some idea of what I'm going to write. It might change along the way--okay, it will PROBABLY change--but I have some kind of clue. This year, I planned to write my first sequel to a previous Nano novel. Unfortunately, my October was so full of busy, I never got a plan together. That's another thing I've learned--you can fly by the seat of your pants through a lot of things, including novels, but not middle books of a three-part series. Those require brain cells and good notes. I have a few of the latter and not nearly enough of the former.
So, once again, I find myself sitting on my couch listening to the "Time Warp" blare from my television, and the only tools I have at my disposal to turn a bunch of words into some kind of art is a notebook and a pen.
At least there is candy.
