December 24th: Finale
Yes, as all intelligent people know, day 24 is the last day of any advent calendar. If you were expecting this to continue on to a twenty-fifth day, please rest assured that I am very disappointed by your massive, massive, ignorance.
Anyway, today's idea is that, if you ever set about making an advent calendar of your ideas, make sure you have more than 23 ideas. Otherwise it will end on a bit of a damp squib, if I'm honest.
