I have an irrational passion for phrasebooks. Whenever I go to a country where I don't know the language I take along a phrasebook. I often take one with me even when I go to a country where I do speak the language. Sometimes in a foreign country I suddenly stop in the middle of the road. People walk into me, but I don't notice because my mind is wholly taken up by the question: Why? What are phrasebooks for?
Perhaps something like this has happened to you. Say it's Tuesday and you are comfortably ensconced in your booth. You have absorbed all the vocabulary you need and the meeting is so routine that most of your mental effort is directed towards using words which are anagrams of the Chairman's name.
