Decembertween - interesting, but just another hijack of the old pre-Christian Yule, Saturnalia and Winter Solstice Festivals. The Catholic Church hijacked those festivals, and then Christmas was hijacked by the juggernaut of modern marketing to become a full-on consumer-fest and now Decembertween ;-)
I guess one must keep up with the times.... To me this time of year is just a great excuse to be with friends and family, eat, drink and generally just enjoy life.
