Here is a good description of a day in Parliament from Don Watson's Recollections of a Bleeding Heart of working for the Keatign Government just after the 1990's recession.
"The government bounced along from a set of encouraging economic figures to a set of bad ones; from an exhilerating spurt to a depressing stumble; from good poll to bad; from good news to gruesome. You would read the press clippings at 9.am and feel confident then read the press clippings at 10 and felt it was hopeless. A kind of progress had made but satisfactory and reliable traction was never achieved. So much emotional turmoil is at least as addictive as it is destructive. Sometimes there was nothing, as if a frame had been cut from the film: everything stopped in mid-stride, instant doldrums, as if one had walked into a black hole in a familar corridor, and a few strides latter the depression---if that's what it is---would lift and the drama would start up again."
Notice how the description is all about emotion not reason. Inside the Prime Minister's Office is run on chaos as well and making it up as you go along. A world of unreason.
