One of my closest friends, and definitely my wisest one, tells me all the time that we, human beings, always tend to assume the worst. In that way, we're prepared for the greatest blow. Anything better than the worst is just a bonus and that makes us happy.
I have always agreed and believed in his theory, and I still do. But what happens when you don't know what would be the worst? What if you aren't sure whether it would be worse if the answer to your unspoken question was a positive or a negative? What if you drew up a mental flowchart and then it just got stuck at one point and stopped flowing any further? What if there was a dead end? Which branch, which tributary, which path of the crossroad would you take then? What would you have assumed when you hadn't known what could be the worst?
