My Minister's room is like a padded cell, and in certain ways I am like a person who is suddenly certified a lunatic and put safely into this great, vast room, cut off from real life.Of course they don't behave quite like nurses, because the Civil Service is profoundly deferentialö'Yes, Minister! No, Minister! If you wish it, Minister!'
