Seasonal greetings to all who are celebrating the longest-running holiday in the world. People have been marking this occasion ever since they were able to make calendars, and I don’t expect that to change as long as there are (moderately) intelligent species inhabiting the planet. The event has always been tricked out with various cultural and mythological decorations, and most of them are entirely charming. (There are some obvious exceptions, like “Rudolph the Red-nosed Reindeer” and store-bought egg nog.) Just don’t let any group claim that their “meaning” of the season is The One True Way. Those silly folks just have no sense of history.
