Whoever leads a solitary life and yet now and then wants to attach himself somewhere, whoever, according to changes in the time of day, the weather, the state of his business, and the like, suddenly wishes to see any arm at all to which he might cling, he will not be able to manage for long without a window looking on to the street. And it he is in the mood of not desiring anything and only goes to his window sill a tired man, with eyes turning from his public to heaven and back again, not wanting to look out and having thrown his head up a little, even then the horses below will draw him down into their train of wagons and tumult, and so at last into the human harmony.
- Kafka, The Complete Stories and Parables
