For several weeks now, Mrs. Chalk and I have been keenly looking forward to the start of the hedonistic frenzy that we indulge in at this time of year. It is a simple game, but it gives us much pleasure (amid the odd accusation of cheating and occasional furious argument) and this year we would like to invite readers to join in the fun.
It's called "Who's behind the door?" and consists of trying to guess what lies behind today's door on our Advent calendar.
The calendar is opened each weekday on Mrs Chalk's return from work, by which time the atmosphere in Chalk Mansions has reached fever pitch.
Feel free to enter your guess each day in the comments box. The person with the most correct answers will receive a prize. Only one guess per player is allowed.
Tips: the calendar is randomly sourced each year by Mrs Chalk's mother. You tend to get a feel for its style after a few goes. Some have more of a religious theme than others. We still reminisce about the Japanese one of 2003.
Remember, you can't win if you're not in! Enter your guess for Dec 1st now.
