Today is Defy Superstition Day! Defying superstition is a pretty easy thing to do. Especially with science. My personal studies show that people who break mirrors are only experiencing a little bit of 'bad luck' only by merit of the fact that their mirror is now broken. There are no further instances of exceptionally bad luck that surface immediately, in the short term, or even in the long term. There may be other instances that aren't exactly fortuitous, but they aren't an effect of the mirror breaking. The event's significance is simply amplified in importance simply because the person experiencing it has written it up as inevitable due to their original mistake of breaking a mirror. I don't know why people do it, though. Maybe we find some comfort in finding any sort of scapegoat to stick all of our downfalls onto so whatever happens to us isn't completely our fault. That way we don't go insane with the knowledge that maybe we do, in fact, stink at handling mirrors.
... Anyway, you can celebrate today by walking under ladders or having a black cat cross your path. It doesn't count if you cross it's path. That's good luck. For the cat.
