I will be doing...nothing, more than likely.
I haven't gone out for Halloween in any fashion since I was in sixth grade (however long ago that was, I don't feel like thinking right now), and thankfully I live in an apartment complex that doesn't have a lot of kids so yay no trick or treaters.
(I got so tired of being the one forced to give out candy when I was still with my parents. Oh, my siblings are suspiciously not there that night? Quick, let's hide in the back and give her the candy bucket, she won't mind!)
