Well it's that most wonderful time of the year when all those so inclined celebrate the mind (though perhaps not the personality) of Isaac the birthday boy. I don't know at what point something becomes a tradition but as this is my third Newtonmas card (see the others
here and
here) I'm going to call this a tradition of mine.
Raise a glass of spiced cider and don't forget the apple on top of your Newtonmas tree this year. Warmest compliments of the season and a very happy new year to everyone!
