Expectation should be synonymous with Emotion. Even if not in the English thesaurus but in the world where a thinking living being is there. You sense - see, smell, hear, touch - any thing, you build an expectation. It is natural as you cannot stop thinking that brings all the emotions out. It can be instantaneous based on instincts or comprehensively cognitive. For me, it is one of the things I know but cannot stop being trapped in the web of emotions build out of expectations. The effect is profound and insane at times. You simply love being the slave of your emotions.
So now I want to experience the other side of coin. Is it possible to shut myself down enough to feel no emotions and then come out of that state to feel the way I feel now? You try meditation, introspection, induced trances but nothing seems to change except moving from one emotional state to another. I guess the day I'll know the answer I'll be something else...lol!
