Xmas Pi and christmas pie. It’s that time of year again. In my neck of the woods Christmas day will be either blistering hot with a chance of late thunderstorms, or wonderfully mild and raining, a respite from the blistering hot days preceding it. I’m hoping for the relief of a cool day, but whatever the weather we will sit outside and feast on prawns and pudding. Wishing good cheer and happy days to everyone.
