While substitute teaching I came across a book of Mark Twain's short stories. "The Diary of Adam and Eve" was hilarious. Witty beyond belief. I now understand more why Mark Twain is so famous. Actually, Dr. Gray (I think his name is) who wrote "Men are From Mars, Women are From Venus" was able to turn such psychological and behavioral characteristics into a multi million dollar enterprise. Twain presented the issue long ago.
