Human beings are full of contradictions. We want what we don’t have. We get tired of what we struggled to get. We say one thing but do another.
It’s not just people who behave this way, throughout the universe things are happening that aren’t supposed to be happening. We think we know how something works and then it does something completely different.
We like patterns, we like working out the rules and being able to predict events. But there’s always an exception to the rule. An anomaly will arise. The unexpected will turn up with alarming regularity. And when this happens our reaction is to take a closer look. We are fascinated by contradiction and want to examine it for answers, even when there are none to be had.
This urge is powerful and is just as strong in the fictional world as it is in the real one.
