Nothing is left to chance...

We don't always know why things happen. Sometimes, the people who did the deed don't even know why they did it. Sometimes, they have a perfectly good reason, and we just don't know it. Sometimes, they do it simply because they can. We don't always understand the reasoning behind things. Sometimes we don't understand the reasoning behind the reasoning. That is just how life goes. Some things we understand in time, and some, we never understand at all.
