I seriously don't understand the whole point in lying to your kids saying there is an obese old man, who never shaves, that slides through chimneys, eats the milk and cookies, and delivers billions of presents to every Christian child in the world in less than milliseconds...
Aww, Mason, bless you.
The tradition to tell your children father Christmas is coming, is years old - it has history to it and it is harmless really, as by the time children find out there is no Father Christmas, they have worked it out anyway.
It just adds to the dream, the whole fantasy of Christmas, the excitement.
Sometimes, as children, all we have is fantasy, to keep us going through life - not as bad as it seems.
