... because no one wants a new calendar once January has already started!
It's easy to think you have plenty of time in September, when you recklessly purchase a couple of blank calendars in Lidl.
And the kids are sick through most of December and not very photogenic as a result.
And then it takes longer than you thought to glue them all in straight. (Or wonky as the mood takes you.)
Just have to remember to take it to the Post Office tomorrow. And hope Royal Mail can get it there before February!
