Something quite extraordinary happened the other day. I would go so far as to say it was a miracle. Not a major one, just a small one - perhaps performed by one of the smaller gods of Discworld.
Actually, perhaps miracles are just chance as defined by chaos theory - remember the monkeys typing Shakespeare? Well, why shouldn't a miracle just be all the things that need to happen falling into line in the right order. That's probably how we got here in the first place - pure chance.
The one thing I DO know about miracles. The moment you start analysing them, they are no longer miracles. If you ask why or how or what, the miracle is gone.
So if something happens, accept it.
You never know, it might be a miracle.
