Nostalgia is a file that removes the rough edges from the good old days.
It isn't necessary to imagine the world ending in fire or ice. There are two other possibilities: one is paperwork, and the other is nostalgia.
I HAVE endeavoured in this Ghostly little book, to raise the Ghost of an Idea, which shall not put my readers out of humour with themselves, with each other, with the season, or with me. May it haunt their houses pleasantly, and no one wish to lay it.
Their faithful Friend and Servant,
Preface of A Christmas Carol by Charles Dickens
