Christmas has passed and, once again, a major question remains unanswered ...
Apparently, Santa knows who's been naughty and who's been nice - but how does he know this?
Is there a troop of elves out there following families, making notes about children's behaviour, taking photographs and spying on neighbourhoods?
Does the man in the red suit hire private investigators? Is this yet another contract passed to Thompson & Clark along with eavesdropping on owners of quake-damaged homes in Christchurch and spying on those with opinions different to the National Party?
If so, how did Santa pay them? With gift vouchers, a stocking full of cheap plonk or a selection of cheeses? I digress from the original question: How does Santa find out who has been naughty and who has, in fact, been nice - and is there some critical balance of naughtiness to niceness that determines whether or not a kid gets toys at Christmas?
