The discussion (if you can call it that) begins around the end of October and normally starts with 'Daaaad, there's this great new toy/game.'
Every parent knows that sinking feeling of dread when your child has picked the only present that they have no chance of getting.
Unless, of course, you queue around the block and sleep in the street for a week to make sure you get one of only 20 released just minutes before closing on Christmas Eve.
In the not so distant past, it was Tracey Island, but this year I have been reliably informed it is the Nintendo Wii.
For those of you who don't have frighteningly well informed teenagers in the family, the Wii is a games console with a difference.
Released just in time for last Christmas, it appears to be still holding its own among this year's top 10 Christmas toys.
Instead of being glued to the sofa giving yourself repetitive strain injury of the thumb playing on a Playstation, you can jump around with the control, playing tennis or any number of games and, of course, give yourself any number of injuries. (Wii wrist is one, as is Wii bruises, when a controller goes flying and hits anyone in the immediate vicinity.)
My son absolutely loves the Wii because it is so interactive and so new and, the cynical parent in me recognises, so well marketed.
But for me as an IT professional, my interest stems from the use of technology in the Wii and the lifestyle trends which have shaped it.
Nintendo appears to have invested millions, if not billions, in developing a product which uses cutting edge technology to play games.
The console uses Bluetooth technology to work wirelessly and online connectivity to update itself.
For many people it represents the most advanced technology they are using at the moment for either work or play.
Nintendo say the development of the Wii was prompted by the urge to get more people playing computer games and, if news reports are correct, they are meeting that target.
According to a recent story, people as old as 103 have been playing with the Wii - a previously untargeted and untapped market for games manufacturers.
And the market reaches up as well as down. I have seen some very adept four-year-olds beating their families hands down on the Wii and these tots had never expressed a minute's interest in the Playstation or other consoles.
Whether the Wii's appeal is its innovation or that it moves away from the traditional, stationery gaming which has been so thoroughly lambasted in the media I don't know.
But the fact that you can burn up a few calories while you jump around the living room can only be of benefit.
But for me the appeal of this smart piece of kit is that it introduced technology to people who, because of their age and interests, have missed some of the fantastic opportunities technology can offer.
In the last five years, technology has changed more quickly than in any period in the previous century, as companies throw more and more money at research and development and offer solutions to problems we didn't know we had.
My job is to take this technology into the workplace, whether it is a school, an office or a factory.
These days, schools are some of the easiest places to walk into with technology because the pupils are so up to speed with the latest advances, and the teachers are not far behind. And in many offices, the revolution has begun.
But if one more person is prepared to meet the challenge of IT thanks to Father Christmas bringing technology into their lives down a chimney, then the Wii is on my Christmas list.
