“By now he had learned. Choices are made in brief seconds and paid for in the time that remains.”

“All he did all afternoon was calculate again and again how many hours of study time he was losing. Thinking about it now, he felt stupid, as we all do when we remember all the time we waste wishing we were somewhere else.”

“She was stung by sharp regret thinking about the sheets and tablecloths, so costly and never used due to excessive regard.”

“Denis's love for Mattia had burned itself out, like a forgotten candle in an empty room, leaving behind a ravenous discontent.”

“Mattia thought that he and Alice were like that, twin primes, alone and lost, close but not close enough to really touch each other.”

“All Mattia saw was a shadow moving toward him. He instinctively closed his eyes and then felt Alice’s hot mouth on his, her tears on his cheek, or maybe they weren’t hers, and finally her hands, so light, holding his head still and catching all his thoughts and imprisoning them there, in the space that no longer existed between them.”

“Prime numbers are divisible only by 1 and by themselves. They hold their place in the infinite series of natural numbers, squashed, like all numbers, between two others, but one step further than the rest. They are suspicious, solitary numbers, which is why Mattia thought they were wonderful. Sometimes he thought that they had ended up in that sequence by mistake, that they'd been trapped, like pearls strung on a necklace. Other times he suspected that they too would have preferred to be like all others, just ordinary numbers, but for some reason they couldn't do it. This second thought struck him mostly at night, in the chaotic interweaving of images that comes before sleep, when the mind is too weak to tell itself lies.”

“By now he had learned. Choices are made in brief seconds and paid for in the time that remains.”

“...finally her hands, so light, holding his head still and catching all his thoughts and imprisoning them there, in the space that no longer existed between them.”

“Mattia's voice no longer stirred anything in his stomach, but he was aware of the idea of him and always would be, as the only true benchmark for everything that had come afterward.”
