A wise man will tell you that no one can every truly tell the future. A truly wide man will tell you that trying to foretell the future automatically alters it for you. But neither of them is as good as the guy sitting in the back of the pub, two pints over the limit, who not only knows the future, but will tell everyone about it. At length. And volume. For forty-five minutes.
Well, I don't know how wise I am, but I do have enough for a couple of pints in my wallet.
