Neil Gaiman on telling your kids about Santa Claus' true identity:
My children have, on occasion, strongly suggested that there might not be a Father Christmas. They also seem very doubtful about the existence of the Tooth Fairy and the Easter Bunny and the Weird Knife Lady In The Attic. I humour them by pretending to go along with all this, but I keep my own counsel on the matter.
