"The left ego is the master of consciousness; the right is master of the unconscious. And the relation between the two is not unlike the relation between Laurel and Hardy in the old movies. Ollie is the left brain, the boss. Stan takes his cues from Ollie. When Ollie is in a good mood, Stan is delighted. When Ollie is depressed, Stan is plunged into the depths of gloom. Stan is inclined to over-react. When Ollie wakes up on a wet Monday morning, he thinks: 'Damn, it's raining, and I've got a particularly dreary day in front of me . . .' Stan overhears this and sinks into depression. And -- since he controls the energy supply -- Ollie has that 'sinking feeling', and he feels drained of energy. This makes him feel worse than ever. As he walks out of the gate he bumps into a man who tells him to look where he is going, then trips over a crack in the pavement, then misses a bus just as he arrives at the stop, and thinks: 'This is going to be one of those days . . .' And again, Stan overhears, and feels worse than ever. by the end of the day, he may be feeling suicidal -- not because things have really been that bad, but because of a continual 'negative feedback' of gloom between the right and the left."
