Nine out of ten times, whenever something unexpected/out of the ordinary happens, it's for the worse. Not necessarily BAD, but let's just say serendipity is in short supply in this life. Not that it is too much of a bother. For someone who spends more time trying to understand the theories that try to sort of almost not really explain everything (a unified theory is nowhere to be found as of yet, so that's probably why) than doing something useful, like say get a job, or go to a university or something, the worst things to happen on a personal level tend to seem quite insignificant, when compared to the stuff that goes on everywhere, all the time.
So it seems the point is that yeah, going to have to say pessimistic. And cynical. And probably nihilistic as well.
