Imagine that you have a very crabby uncle. One day he says he saw ghosts. Not one ghost, but three ghosts. Now he's a changed man. What would you do? You might very well take your uncle to a psychologist.
A Christmas Carol was published in 1843. The book is as popular today as it was over 150 years ago. Dickens, through the voice of Scrooge, continues to urge us to honor Christmas in our hearts and to keep the season in mind all the year round.
