He suddenly recalled from Plato's Symposium: People were hermaphrodites until God split then in two, and now all the halves wander the world over see… - Milan Kundera

...people don't respect the morning. An alarm clock violently wakes them up, shatters their sleep like the blow of an ax, and they immediately surrender themselves to deadly haste. Can you tell me what kind of day can follow a beginning of such violence? What happens to people whose alarm clock daily gives them a small electric shock? Each day they become more used to violence and less used to pleasure.

From that time on they both looked forward to sleeping together. I might even say that the goal of their lovemaking was not so much pleasure as the sleep that followed it. She especially was affected. Whenever she stayed overnight in her rented room (which quickly became only an alibi for Tomas), she was unable to fall asleep; in his arms she would fall asleep no matter how wrought up she might have been. He would whisper impromptu fairy tales about her, or gibberish, words he repeated monotonously, words soothing or comical, which turned into vague visions lulling her through the first dreams of the night. He had complete control over her sleep: she dozed off at the second he chose.

Not even one's own pain weighs so heavy as the pain one feels with someone, for someone, a pain intensified by the imagination and prolonged by a hundred echoes.
