If you haven't tried this... here is a tip. If you discovered the whole Santa bit is just a trip then don't say you've discovered it quite yet, keep believing so you get more gifts because then mum and dad have to buy a gift from them and Santa too.
That's just plain 'evil' and what are you in sighting the young minds to do eh? There are some parents who don't believe in telling their children about Santa Claus so that might save you from getting away with this.
