As usual, I will spend the day and evening as a middle aged librarian. Very scary stuff, indeed.
This year, though, I plan on adding a pair of elf ears.

I have a thing about elves. I have some very intriguing cartilage at the top of my ears and have always told the kids that I'm a half-elf -- sometimes they almost believe me

I couldn't resist some rubber ear tips that look as though they belong on my head. I'll be waiting to see how many people I freak out at the reference desk. Or, even better, whether anyone even notices!!
And then I'll come home and deal with an overwrought vampiress and ... get this... Tinkerbell. *groan* She was supposed to be Inuyasha this year. But chose Tinkerbell.
I have.. failed... as an anime parent...
