In Iceland, books are exchanged as Christmas Eve presents, then you spend the rest of the night in bed reading them and eating chocolate. The tradition is part of a season called Jolabokaflod, or ‘The Christmas Book Flood’,
Or when they don't know their favorite character is about to die because they really aren't and you tell them they are and they believe you. It's the most hilarious thing in the world. except it was the book I was working on.
