Paolo Giordano - The Solitude of Prime Numbers

Mattia let go of Alice's hand. It was as if all his nerve endings were concentrated in that single point, and when he broke away, it seemed that his arm gave off sparks, as if from a bared cable.

"Excuse me," he whispered to her and left the kitchen to catch up with Denis.

Alice walked over to Viola, who was staring at her with eyes of stone.

"We-" she began.

"I don't care," Viola cut in. Looking at Alice and Mattia, she had remembered the boy at the beach, the moment when he had refused to hold her hand, while she would have loved to go back to the others on the beach holding hands just like that. She was jealous, a painful, violent jealousy. And she was furious, because the happiness she wanted for herself she had just given to someone else. She felt robbed, as if Alice had taken her share too.

Alice leaned over to say something in her ear, but Viola turned away.

"What do you want now?" she said.

"Nothing." Alice retreated in fear.

At that moment Giada bent forward, as if an invisible man had punched her in the stomach. With one hand she held on to the kitchen counter and with the other she gripped her belly.

"What's wrong?" Viola asked.

"I'm going to throw up," she moaned.

"Gross, go to the bathroom," Viola yelled.

But it was too late. With a jerk Giada emptied the contents of her stomach onto the floor, something reddish and alcoholic, a mixture of vodka and Soledad's dessert.

The others pulled back, horrified, while Alice tried to hold her up by the hips. The air immediately turned rancid.

"Well done, you idiot," said Viola. "What a fucking awful party."

She left the room, her fists clenched furiously, as if struggling to keep from smashing something. Alice looked at her anxiously and then went back to taking care of Giada, who was sobbing gently.

The other guests had scattered about in small groups around the living room. Most of the boys were bobbing their heads back and forth to the music, while the girls scanned the room. Some held drinks in their hands; six or seven were dancing to "A Question of Time." Mattia wondered how they could feel so at ease, moving around like that in front of everyone. Then he realized it was the most natural thing in the world, which was precisely why he was incapable of it.

Denis had disappeared. Mattia crossed the living room and went to look for him in Viola's room. He even looked in her sister's and her parents' rooms. He looked in both bathrooms and in one he found a boy and a girl from school. She was sitting on the toilet and he was on the floor in front of her, legs crossed. They both wore sad and questioning expressions and Mattia hastily closed the door.

He went back to the living room and out onto the balcony. The hill dropped away darkly and below them lay the entire city, a series of bright white dots arranged homogeneously, as far as the eye could see. Mattia leaned over the railing and looked through the trees of the grounds of Villa Bai, but he couldn't see anyone. He went back inside; anxiety began to shorten his breath.

A spiral staircase led from the sitting room to a dark attic. He climbed the first steps, then stopped.

Where has he gotten to? he thought.

He went on, up to the top. The light that filtered from below allowed him to make out the shadow of Denis, standing in the middle of the room.

He called to him. All through their friendship he had uttered his name only two or three times at the most. He had never needed to, because Denis was always right next to him, like a natural extension of his limbs.

"Go away," Denis replied.

Mattia looked for the switch and turned on the light. The room was enormous, lined with tall bookshelves. The only other furniture was a big, empty wooden desk. Mattia had the impression that no one had come up to this floor of the house for a long time.

"It's almost eleven. We have to go," he said.

Denis didn't reply. His back was turned, and he stood in the middle of a big rug. Mattia walked over to his friend. He saw that Denis had been crying. He was blowing through his teeth as he breathed, his eyes fixed straight ahead and his half-open lips trembling slightly.

It took Mattia a few seconds to notice a desk lamp that lay shattered at his feet.

"What have you done?" he asked.

Denis's breathing turned into a wheeze.

"Denis, what have you done?"

Mattia tried to touch his friend's shoulder, but Denis gave a violent start. Mattia shook him.

"What have you done?"

"I…" Denis began. Then he froze.

"You what?"

Denis opened his left hand and showed Mattia a fragment of the lamp, a splinter of green glass, grown opaque from sweat, that seemed to swallow up the light.

"I wanted to feel what you feel," he whispered.

Mattia didn't understand. He stumbled back, confused. A burning sensation exploded in his gut and filled his arms and legs.

"But then I couldn't do it," said Denis.

He held the palms of his hands upward, as if waiting for something.

Mattia was about to ask him why, but didn't. The music rose up, muffled, from below. The low frequencies passed through the floor, but the higher ones seemed trapped.

Denis sniffed. "Let's get out of here," he said.

Mattia nodded, but neither of them made a move. Then Denis turned and abruptly walked toward the stairs. Mattia followed him across the living room and then outside, where the cool night air was waiting to give them back their breath.

Viola decided if you were in or out. On Sunday morning Giada Savarino's father had phoned Viola's father, waking up the entire Bai household. It was a long phone call and Viola, still in pajamas, had pressed her ear to her parents' bedroom door, but she hadn't been able to catch a single word of the conversation.

When she heard the bed creak, she had run back to her room and hid under the blankets, pretending to be asleep. Her father had woken her up saying you can tell me what happened later, but for now let me tell you that there will be no more parties in this house and, in fact, you can forget about parties of any kind for a good long while. At lunch her mother had asked her to explain the broken lamp in the attic and her sister hadn't come to her defense, because she had noticed that Viola had laid her hands on her personal stock.

She locked herself away in her room all day, disheartened and banned from using the phone. She couldn't get Alice and Mattia, and their way of holding hands, out of her head. As she scratched away the last remnants of nail polish she decided: Alice was out.

On Monday morning, locked in her bathroom at home, Alice finally removed the gauze that covered her tattoo. She balled it up and then threw it in the toilet, along with the crumbled biscuits that she hadn't eaten for breakfast.

She looked at the violet reflected in the mirror and thought that, for the second time, she had changed her body forever. She shivered with a pleasant mixture of regret and trepidation. She thought that this body was hers alone, that if she felt like it she could even destroy it, lay waste to it with indelible marks, or let it dry out like a flower picked on a whim by a child and then left to die on the ground.

That morning she would show her tattoo to Viola and the others, in the girls' bathroom. She would tell them how she and Mattia had kissed for a long time. There was no need to invent anything more than that. If they asked her for details, she would merely go along with their fantasies.

In class she left her backpack on her chair and headed over to Viola's desk to join the others. As she approached, she heard Giulia Mirandi saying here she comes. She said hi to everyone, beaming, but no one replied. She leaned over to give Viola two kisses on the cheeks, as Viola had taught her to do, but her friend didn't move an inch.
