There is a guy in my neighborhood that puts out a Festivus pole in front of his house every year. It's on a busy street, just a couple blocks up from a Catholic church, so he knows what he's about. I appreciate that, because I reject both the bullshit religiosity and the bullshit commercialism that typifies most Christmas events.
I remain a fan of the Winter Solstice celebration as gift exchange (and because it's fun when the days start trending brighter), and also the reminder that you should do something nice for people you care about, maybe take some time to sit with them and enjoy that experience. Or punish yourself and hang out with family members and in laws that you don't like. Up to you.
Whatever you end up doing I hope you had a good 2016, and that 2017 makes you rich in happiness and friendship.
