Is possible that one of them said so but only one person heard it right? and from the library the witnesses said things that only a couple of people heard and is something that they could heard wrong or misunderstood. We only can speculate then because it could happened but I dont know, this is one of those claims that I put on the list of "conversations from library that supposedly took place but could be a product of the whole chaotic situation"

The most terrifying fact about the universe is not that it is hostile but that it is indifferent; but if we can come to terms with this indifference and accept the challenges of life within the boundaries of death — however mutable man may be able to make them — our existence as a species can have genuine meaning and fulfillment. However vast the darkness, we must supply our own light
