Two of the most popular schools of thought as to how the world works are referred to as order and chaos. While I am not going to go on a philosophical rant and try to prove one case or the other, I will say that in some cases, the events which are unfolding seem chaotic only because we do not know where they originated from.
It looks like they are happening randomly, but that is only because we are not aware of the logical chain of events which led up to that point. In the end, everyone is the protagonist in his or her own story, and we all set events in motion, and in some cases they collide; perhaps we shouldn’t be so surprised at unlikely and seemingly-chaotic events occurring.
