“To me, it was clear proof of the existence of supersymmetry, the idea that every particle has a partner. She was mine.”

“Yeah!' I said again, widening my eyes and nodding slowly but emphatically to show that she had seen into my own symmetrical soul.”

“I couldn't decide what kind of person she was, whether she was one of those insects that look exactly like wasps but aren't . . . I just wanted to know if she would sting.”

“To me, it was clear proof of the existence of supersymmetry, the idea that every particle has a partner. She was mine.”

“In the last week I felt her withdrawing. What was once everywhere, an ocean I imagined myself to be drowning in, was now barely deep enough to bathe in. I saw her warmth draining away and I couldn't stop it.”

“There was never one truth. Even the Higgs could still be used to prove opposing theories, its mass falling between them on a chart. Besides, I told myself, my breathing heavy, eyes widening until they bulged, I was post-truth.”

“Waking in the morning, I had to remember grief all over again. It was sunny, a white winter sun, and that made me sad.”

“It's hard to explain how an infatuation actually starts. It's a state so all-encompassing that it's almost impossible to remember how it felt to live inside your own head before it began. Everything that precedes it becomes a pathway that was always leading there. Time before is valuable only as a resource with which to create a persona, to bind the object of the infatuation closer. I had given my (partially fabricated) past life to Mizuko to make a story that in the end never got told. Or not by her. It is also hard to explain the intensity of the infatuation itself. There is rarely an explanation that seems reasonable to anyone but you. Unless you're part of a cult or viral phenomenon, so that when you weep outside the object of your infatuation's hotel room, you do so in the company of millions.”

“Suddenly I had to laugh. It was like realising you definitely need to projectile vomit when you thought you had it under control in some imprisoning form of public space.”

“We had, I felt, bared small pieces of our symmetrical souls to each other, fast, as if playing one of those breathless card games, and I had pretended to be as moved as I had been the first time I uncovered it all myself, back in East Hampton.”

“I felt the nauseous shiver in my stomach—everything from rage to empathy to morning sickness—that I had grown used to and now thought of as being love.”
