“There are many types of monsters that scare me: Monsters who cause trouble without showing themselves, monsters who abduct children, monsters who devour dreams, monsters who suck blood... and then, monsters who tell nothing but lies. Lying monsters are a real nuisance: They are much more cunning than others. They pose as humans even though they have no understanding of the human heart; they eat even though they've never experienced hunger; they study even though they have no interest in academics; they seek friendship even though they do not know how to love. If I were to encounter such monsters, I would likely be eaten by them... because in truth, I am that monster.” Who said this?
