"If it was an emotion, it was a totally emotionless one. It was hatred, implacable hatred. It was cold, not like ice is cold, but like a wall is cold. It was impersonal, not as a randomly flung fist in a crowd is impersonal, but like a computer-issued parking summons is impersonal. And it was deadly - again, not like a bullet or a knife is deadly, but like a brick wall across a motorway is deadly."
- Douglas Adams
