Nanny Ogg could see the future in the froth on a beer mug. It invariably showed that she was going to enjoy a refreshing drink which she almost certainly was not going to pay for.
Terry PratchettPeople look down on stuff like geography and meteorology, and not only because they're standing on one and being soaked by the other. They don't look quite like real science. But geography is only physics slowed down and with a few trees stuck on it, and meteorology is full of excitingly fashionable chaos and complexity. And summer isn't a time. It's a place as well. Summer is a moving creature and likes to go south for the winter.
