People were stupid, sometimes. They thought the Library was a dangerous place because of all the magical books, which was true enough, but what made it really one of the most dangerous places there could ever be was the simple fact that it was a library.
Terry PratchettDogs are not like cats, who amusingly tolerate humans only until someone comes up with a tin opener that can be operated with a paw. Men made dogs, they took wolves and gave them human things - unnecessary intelligence, names, a desire to belong, and a twitching inferiority complex. All dogs dream wolf dreams, and know they're dreaming of biting their Maker. Every dog knows, deep in his heart, that he is a Bad Dog.
