‘Pessimistic. It means looking only at the dark side of things.’
‘Pessimistic … pessimistic …’ She repeated the English to herself over and over, and then she looked up at me with a fierce glare. ‘I’m only sixteen,’ she said, ‘and I don’t know much about the world, but I do know one thing for sure. If I’m pessimistic, then the adults in this world who are not pessimistic are a bunch of idiots.’"
Haruki Murakami, The Wind-Up Bird Chronicle
