He never spent the night with the others. It was easy enough if he was at their place: he could leave whenever he pleased. It was worse when they were at his and he had to explain that come midnight he would have to drive them home because he was an insomniac and found it impossible to fall asleep in close proximity to another person. Though it was not far from the truth, he never dared tell them the whole truth: after making love he had an uncontrollable craving to be by himself; waking in the middle of the night at the side of an alien body was distasteful to him, rising in the morning with an intruder repellent; he had no desire to be overheard brushing his teeth in the bathroom, nor was he enticed by the thought of an intimate breakfast.

The unwritten contract of erotic friendship stipulated that Tomas should exclude all love from his life. The moment he violated that clause of the contract, his other mistresses would assume inferior status and become ripe for insurrection.

Accordingly, he rented a room for Tereza and her heavy suitcase. He wanted to be able to watch over her, protect her, enjoy her presence, but felt no need to change his way of life. He did not want word to get out that Tereza was sleeping at his place: spending the night together was the corpus delicti of love.

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.

While they slept, she held him as on the first night, keeping a firm grip on wrist, finger, or ankle. If he wanted to move without waking her, he had to resort to artifice. After freeing his finger (wrist, ankle) from her clutches, a process which, since she guarded him carefully even in her sleep, never failed to rouse her partially, he would calm her by slipping an object into her hand (a rolled-up pajama top, a slipper, a book), which she then gripped as tightly as if it were a part of his body.

That is why he was so surprised to wake up and find Tereza squeezing his hand tightly. Lying there looking at her, he could not quite understand what had happened. But as he ran through the previous few hours in his mind, he began to sense an aura of hitherto unknown happiness emanating from them.

Once, when he had just lulled her to sleep but she had gone no farther than dream's antechamber and was therefore still responsive to him, he said to her, Good-bye, I'm going now. Where? she asked in her sleep. Away, he answered sternly. Then I'm going with you, she said, sitting up in bed. No, you can't. I'm going away for good, he said, going out into the hall. She stood up and followed him out, squinting. She was naked beneath her short nightdress. Her face was blank, expressionless, but she moved energetically. He walked through the hall of the flat into the hall of the building (the hall shared by all the occupants), closing the door in her face. She flung it open and continued to follow him, convinced in her sleep that he meant to leave her for good and she had to stop him. He walked down the stairs to the first landing and waited for her there. She went down after him, took him by the hand, and led him back to bed.

Tomas came to this conclusion: Making love with a woman and sleeping with a woman are two separate passions, not merely different but opposite. Love does not make itself felt in the desire for copulation (a desire that extends to an infinite number of women) but in the desire for shared sleep (a desire limited to one woman).
