― José Donoso, The Obscene Bird of Night
"There, there, you're not always necessarily you" - Dempow Torishima, Sisyphean
“Mario, what do you get when you cross an insomniac, an unwilling agnostic and a dyslexic?"
"I give."
"You get someone who stays up all night torturing himself mentally over the question of whether or not there's a dog.”
― David Foster Wallace, Infinite Jest
