"Love isn’t something that we invented. It’s observable. Powerful. It has to mean something. Maybe it means something more, something we can’t yet understand. Maybe it’s some evidence, some artifact of a higher dimension that we can’t consciously perceive. Love is the one thing that we’re capable of perceiving that transcends dimensions of time and space." - Interstellar

Murphy's law doesn't mean that something bad will happen. It means that whatever can happen, will happen.
