All that sort of thing could be put up with, it belonged to the ordinary continual petty annoyances of life, it was nothing compared with what K. was striving for, and he had not come here simply to lead an honoured and comfortable life.
— Kafka, The Castle (tr. W. and E. Muir)
Everyone carries a room about inside him. This fact can even be proved by means of the sense of hearing. If someone walks fast and one pricks up one's ears and listens, say in the night, when everything round about is quiet, one hears, for instance, the rattling of a mirror not quite firmly fastened to the wall.
– Kafka
