I want to comment briefly on the title of this message, How To Hug. This was suggested to me by a story I once heard about a man who was walking down the street. He passed a used book store, and in the window he saw a book with this title, How To Hug. He was taken by the title and, being of a somewhat romantic nature, went in to buy the book. To his chagrin, he discovered that it was the third volume of an encyclopedia and covered the subjects How to Hug.
