I didn’t know what to answer. I already knew how to kiss, didn’t I? Was there something more to learn? But while these questions were going through my head, Clementine was going ahead with the lesson. She came around to face me. With a grave expression she put her arms around my neck.

The necessary special effects are not in my possession, but what I’d like for you to imagine is Clementine’s white face coming close to mine, her sleepy eyes closing, her medicine-sweet lips puckering up, and all the other sounds of the world going silent—the rustling of our dresses, her mother counting leg lifts downstairs, the airplane outside making an exclamation mark in the sky—all silent, as Clementine’s highly educated, eight-year-old lips met mine.

And then, somewhere below this, my heart reacting.

Not a thump exactly. Not even a leap. But a kind of swish, like a frog kicking off from a muddy bank. My heart, that amphibian, moving that moment between two elements: one, excitement; the other, fear. I tried to pay attention. I tried to hold up my end of things. But Clementine was way ahead of me. She swiveled her head back and forth the way actresses did in the movies. I started doing the same, but out of the corner of her mouth she scolded, “You’re the man.” So I stopped. I stood stiffly with arms at my sides. Finally Clementine broke off the kiss. She looked at me blankly a moment, and then responded, “Not bad for your first time.”

“Mo-om!” I shouted, coming home that evening. “I made a friend!” I told Tessie about Clementine, the old rugs on the walls, the pretty mother doing exercises, omitting only the kissing lessons. From the beginning I was aware that there was something improper about the way I felt about Clementine Stark, something I shouldn’t tell my mother, but I wouldn’t have been able to articulate it. I didn’t connect this feeling to sex. I didn’t know sex existed. “Can I invite her over?”

“Sure,” said Tessie, relieved that my loneliness in the neighborhood was now over.

“I bet she’s never seen a house like ours.”

And now it is a cool, gray October day a week or so later. From the back of a yellow house, two girls emerge, playing geisha. We have coiled up our hair and crossed take-out chopsticks in it. We wear sandals and silk shawls. We carry umbrellas, pretending they’re parasols. I know bits of The Flower Drum Song, which I sing as we traverse the courtyard and mount the steps to the bathhouse. We come in the door, failing to notice a dark shape in the corner. Inside, the bath is a bright, bubbling turquoise. Silk robes fall to floor. Two giggling flamingos, one fair-skinned, the other light olive, test the water with one toe each. “It’s too hot.” “It’s supposed to be that way.” “You first.” “No, you.” “Okay.” And then: in. Both of us. The smell of redwood and eucalyptus. The smell of sandalwood soap. Clementine’s hair plastered to her skull. Her foot appearing now and then above the water like a shark fin. We laugh, float, waste my mother’s bath beads. Steam rises from the surface so thick it obscures the walls, the ceiling, the dark shape in the corner. I’m examining the arches of my feet, trying to understand what it means that they have “fallen,” when I see Clementine breasting through the water to me. Her face appears out of the steam. I think we’re going to kiss again, but instead she wraps her legs around my waist. She’s laughing hysterically, covering her mouth. Her eyes widen and she says into my ear, “Get some comfort.” She hoots like a monkey and pulls me back onto a shelf in the tub. I fall between her legs, I fall on top of her, we sink . . . and then we’re twirling, spinning in the water, me on top, then her, then me, and giggling, and making bird cries. Steam envelops us, cloaks us; light sparkles on the agitated water; and we keep spinning, so that at some point I’m not sure which hands are mine, which legs. We aren’t kissing. This game is far less serious, more playful, free-style, but we’re gripping each other, trying not to let the other’s slippery body go, and our knees bump, our tummies slap, our hips slide back and forth. Various submerged softnesses on Clementine’s body are delivering crucial information to mine, information I store away but won’t understand until years later. How long do we spin? I have no idea. But at some point we get tired. Clementine beaches on the shelf, with me on top. I rise on my knees to get my bearings—and then freeze, hot water or not. For right there, sitting in the corner of the room—is my grandfather! I see him for a second, leaning over sideways—is he laughing? angry?—and then the steam rises again and blots him out.

I am too stunned to move or speak. How long has he been there? What did he see? “We were just doing water ballet,” Clementine says lamely. The steam parts again. Lefty hasn’t moved. He’s sitting exactly as before, head tilted to one side. He looks as pale as Clementine. For one crazy second I think he’s playing our driving game, pretending to asleep, but then I understand that he will never play anything ever again . . .

And next all the intercoms in the house are wailing. I shout to Tessie in the kitchen, who shouts to Milton in the den, who shouts to Desdemona in the guest house. “Come quick! Something’s wrong with papou!” And then more screaming and an ambulance flashing its lights and my mother telling Clementine it’s time for her to go home now.

Later that night: the spotlight rises on two rooms in our new house on Middlesex. In one pool of light, an old woman crosses herself and prays, while in the other a seven-year-old girl is also praying, praying for forgiveness, because it was clear to me that I was responsible. It was what I did . . . what Lefty saw . . . And I am promising never to do anything like that again and asking Please don’t let papou die and swearing It was Clementine’s fault. She made me do it.

(And now it’s time for Mr. Stark’s heart to have its moment. Its arteries coated with what looks like foie gras, it seizes up one day. Clementine’s father crumples forward in the shower. Down on the first floor, sensing something, Mrs. Stark stops doing leg lifts; and three weeks later she sells the house and moves her daughter away. I never saw Clementine again . . .)

Lefty did recover and came home from the hospital. But this was only a pause in the slow but inevitable dissolution of his mind. Over the next three years, the hard disk of his memory slowly began to be erased, beginning with the most recent information and proceeding backward. At first Lefty forgot short-term things like where’d he put down his fountain pen or his glasses, and then he forgot what day it was, what month, and finally what year. Chunks of his life fell away, so that while we were moving ahead in time, he was moving back. In 1969 it became clear to us that he was living in 1968, because he kept shaking his head over the assassinations of Martin Luther King, Jr., and Robert Kennedy. By the time we crossed over into the valley of the seventies, Lefty was back in the fifties. Once again he was excited about the completion of the St. Lawrence Seaway, and he stopped referring to me altogether because I hadn’t been born. He reexperienced his gambling mania and his feelings of uselessness after retiring, but this soon passed because it was the 1940s and he was running the bar and grill again. Every morning he got up as though he were going to work. Desdemona had to devise elaborate ruses to satisfy him, telling him that our kitchen was the Zebra Room, only redecorated, and lamenting at how bad business was. Sometimes she invited ladies from church over who played along, ordering coffee and leaving money on the kitchen counter.

In his mind Lefty Stephanides grew younger and younger while in actuality he continued to age, so that he often tried to lift things he couldn’t or to tackle stairs his legs couldn’t climb. Falls ensued. Things shattered. At these moments, bending to help him up, Desdemona would see a momentary clarity in her husband’s eyes, as if he were playing along too, pretending to relive his life in the past so as not to face the present. Then he would begin to cry and Desdemona would lie down next to him, holding him until the fit ended.
