Besides being the Second Day of Christmas and the Feast of St Stephen, today is also Boxing Day. What, my American readers may ask, is Boxing Day? According to the OED, it is the first week-day after Christmas-day, observed as a holiday on which post-men, errand-boys, and servants of various kinds expect to receive a Christmas-box.
When I was a boy, my Hampshire born Mum always left a jar of jam, fruit, pickles or some such goodie in the mailbox for the postman.
And, if you live in the Old Commonwealth, it is a legal, statutory, or bank holiday mostly devoted to shopping. So, to all my readers in CANZUK, don't spend too much money on the Boxing Day sales!
