Why do you call me a pessimist? I'm a realist, baby. Life just is horrible and agonizing sometimes. That's an observation, a precise prediction, a fact. Tell me what is so wrong about expecting the worst, about protecting yourself. Oh now I'm selfish? Nothing wrong with that. You can never be sure about anything or anybody. Certainty is an illusion. So it's best to keep a safe distance, care for yourself. A lonely lifestyle? Well, you have got to make some sacrifices.
