“...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.”

“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.”

“Every time she heard the click of the shutter, followed by that faint rustle, she remembered when she used to catch grasshoppers in the garden of their house in the mountains when she was a little girl, trapping them between her cupped hands. She thought that it was the same with photographs, only now she seized time and fixed it on celluloid, capturing it halfway through its jump toward the next moment.”

“but his eyes were too dark for her to make out any spark in them”

“Mathematicians call them twin primes: pairs of prime numbers that are close to each other, almost neighbors, but between them there is always an even number that prevents them from truly touching. Numbers like 11 and 13, like 17 and 19, 41 and 43. If you have the patience to go on counting, you discover that these pairs gradually become rarer. You encounter increasingly isolated primes, lost in that silent, measured space made only of ciphers, and you develop a distressing presentiment that the pairs encountered up until that point were accidental, that solitude is the true destiny. Then, just when you’re about to surrender, when you no longer have the desire to go on counting, you come across another pair of twins, clutching each other tightly. There is a common conviction among mathematicians that however far you go, there will always be another two, even if no one can say where exactly, until they are discovered.Mattia thought that he and Alice were like that, twin primes, alone and lost, close but not close enough to really touch each other. He had never told her that. When he imagined confessing these things to her, the thin layer of sweat on his hands evaporated completely and for a good ten minutes he was no longer capable of touching anything.”

“The whole house, its very walls, was impregnated with a smell of vitality that he was unused to. He thought about his own apartment, where it was so easy to decide simply not to exist.”

“His scars were hidden and safe in her hand.”
