People need to play. They need diversion. They need a good excuse to be silly. Enter, Halloween. Of course, reading books of fiction, going to theatre (doing theatre!), singing, scrapbooking, photography, just about anything creative is so good for the whole person.
But there is something uniquely magical about being served by a barista wearing a viking hat, or the store clerk in a super hero cape, or the guy at the credit union in a padded muscle man shirt.
It's simple, and silly. There's not enough of that in the world. Doesn't mean we stop taking care of business. And by "business," I mean feeding the hungry, caring for the environment, helping those with mental illness and addiction, and other issues that help to create a healthy social climate.
But at Halloween, most definitely, put that giant pretend spider web on your front porch and enjoy the fact that we're all pretending about something.
Just don't drive to work in a witch's hat. (Headroom. You can put it on when you get out of the car.)
