I was thinking about the concept of a happy ship, and it is indeed true that most of the Cunard staff I have encountered are either brilliant actors or are indeed happy (most of the time) in their work. I contrast this with my own career as a teacher in nice schools of a subject I find genuinely fascinating. The only time I can ever remember feeling happy was at about 3.45 on a Friday afternoon and during the holidays. This was a pretty widespread sentiment. So, if they are happy, it is more, I think, than most people are, and quite astounding.
