Your heart is like a great river after a long spell of rain, spilling over its banks. All signposts that once stood on the ground are gone, inundated and carried away by that rush of water. And still the rain beats down on the surface of the river. Every time you see a flood like that on the news you tell yourself: That’s it. That’s my heart.
— Kafka on the Shore (Haruki Murakami, 2005)
