Halloween mostly because I tired of Christmas. I did actually kind of like Christmas just as a time to visit family, but it has engulfed Thanksgiving and become a 2 month celebration. Probably the only reason Christmas doesn't become bigger is it can't really combine with something like Halloween.
Now aside from that, I do enjoy Horror and I make it an extra point to enjoy horror fiction and films or discuss Classic Horror or authors like Lovecraft and Poe. Last Fall, I made it a point to watch the original Texas Chainsaw Massacre which is an older horror film I had never seen before despite Leatherface being such an iconic horror character. I'm glad I saw it, it was really different.
I was also trying to promote horror while still on Facebook, but didn't get much response from my boring relatives. Oh well, their loss.
I have also enjoyed having the occasional Oktoberfest seasonal beer, hot apple cider, or other Fall seasonal foods.
Also, while I try to not indulge to much in candy, I do really enjoy Reese's once in a while.
