I suppose it really just boils down to the festivities of it all, and really expressing yourself. You get to create a kick-ass party or decorate your home, but you don't have to make it a special holiday thing. Thanksgiving is for family, Christmas (or equivalent) is for everyone you care about. But Halloween is for fun. It's id satisfaction. Drink up, get crazy on sugary treats, and throw on some music, everyone else is. How very secular.
But there is also the darker tone to the holiday. This is the one day of the year goth kids are happy, it seems. Demons, devils, zombies and monsters. All sorts of abominations come and take this stage at this point of the year, and this makes me very happy, actually. A deep-seated brooding monster blights us all, I think. I feel like this is a special time to go ahead and open the bottle from my teenage years, and let said monster out for a little while.
This year, I'm making my most elaborate costume ever. It will probably be gotten by a maximum of 5 people attending Dr. Girlfriend's Halloween Party, but it's something I may be able to use again for conventions or something. Steam-punk Dr. Horrible, complete with Chronocryonic Blaster (Freeze-Ray.)
This is going to be AWESOME!
