"Isolation has carved me in its image and likeness. The presence of another person - of any person whatsoever - instantly slows down my thinking, and while for a normal man contact with others is a stimulus to spoken expression and wit, for me it is a counterstimulus, if this compound word be linguistically permissible. When all by myself, I can think of all kinds of clever remarks, quick comebacks to what no one said, and flashes of witty sociability with nobody. But all of this vanishes when I face someone in the flesh: I lose my intelligence, I can no longer speak, and after half an hour I just feel tired. Yes, talking to people makes me feel like sleeping. Only my ghostly and imaginary friends, only the conversations I have in my dreams, are genuinely real and substantial, and in them intelligence gleams like an image in a mirror."
