Truth is, no matter how optimistic I put myself to show, some, if not most, part of me is really a pessimist. This sentence in its own right, and like many others we make, are realistic.
We're never simply one of the three at any one time. An optimist would leave the door unlocked; a realist will know the constant risk of burglary even with the door locked; a pessimist will double lock it and still live in constant fear. Since we never leave the door unlocked nor think about the imaginary burglar (and the risk of it being real) every single second (ah, now you're thinking bout it), isn't it then true that we don't belong to any of the above categories?
