The Abstinence Teacher. Tom Perrotta

to Manhattans, a much safer bet. While Randall mixed her drink, Ruth picked up a MotoPhoto envelope resting on the table and shuffled through the pictures, which documented the Massachusetts wedding of Dan and Jerry, two of Randall and Gregory's oldest friends. They made for a striking pair, one man tall and bald and amiable in a black tux, the other in white, bearded and stocky and a bit too intense. The two grooms danced cheek to cheek, fed each other cake, and posed with their elderly parents, who smiled gamely, if a bit uncomfortably, at the camera. Randall had found the ceremony to be incredibly moving—like a dream, he said—while Gregory took a darker view, knowing what he did about Dan and Jerry's troubled relationship.

      “These guys break up every six months or so,” he said. “They only get back together because they're so devoted to making each other unhappy.”

      Ruth laughed. “Sounds like a lot of couples I know.”

      “Dan and Jerry have every bit as much right to a bad marriage as anyone else,” Randall said.

      “People shouldn't get married just because they can,” Gregory said.

      Randall glared at him, his face flushed from a combination of alcohol and anger.

      “Everything doesn't have to be perfect, you know. You just have to love each other for better or worse.”

      Gregory turned to Ruth. “This is about us, you know. He's mad at me for not proposing.”

      “I'm not mad ax. you,” Randall insisted. “I just can't figure out why you're so scared. We've been together for twelve years.”

      “I'm not scared,” Gregory said. “I just don't see the point of getting engaged if we can't get married.”

      “We're making a commitment,” Randall said. “Once it's legal, we'll be first in line.”

      “Let's cross that bridge when we get to it,” Gregory said.

      “Forget it.” Randall's face tightened into an unconvincing smile. “It's really not worth fighting about.”

      “Who's fighting?” said Gregory. “We're having a calm discussion.”

      Randall drained his martini.

      “Let's just watch the movie.”

      It was already after ten. Ruth tried to make a graceful exit, but Randall insisted she at least watch the first ten minutes, where Margaret did the hilarious imitation of her crazy Korean mother. She reluctantly agreed, but then got sucked in and stayed to the bitter end, by which point both her hosts had fallen asleep—Gregory dozing in an armchair, hands resting on his belly, and Randall snoring softly on the couch, his face naked, almost babyish, without his glasses. It didn't look to Ruth like anyone would be breaking out the dog collars anytime soon. She kissed them both good night and showed herself to the door.

      RUTH MADE a point of sleeping in the nude when her daughters were out of the house. It was a simple indulgence, and, sadly enough, the erotic highlight of her week. This private ritual—shedding her clothes in the dark, slipping between the cool sheets, savoring the soft touch of cotton against her skin—had come to seem like a kind of foreplay, automatically nudging her toward that vibrant fantasy realm that, by default, was her sole source of sexual pleasure. And if these fantasies sometimes inspired her to break out the vibrator she kept hidden in a shoe box on a high shelf in her closet, well, so what? It was her body— her lean, muscular, lovely, unloved body—and didn't it deserve to feel good every once in a while, especially if there was no one around to overhear the humming of the busy little machine, or the grateful cries of a woman who had no one to thank but herself?

      Tonight, though, her mind was elsewhere. She lay in the dark, exhausted and wired at the same time, her eyes wide open, the weight of solitude pressing down on her like a heavy blanket. She missed her daughters, wondered if the house would always feel this empty when they left for college, vast and unmoored, ready to lift away from its foundation like a hot-air balloon. She comforted herself with the thought that she still had seven years before Maggie graduated high school, long enough to make some changes. Maybe there'd be a man by then; maybe the exodus of the girls would feel more like a honeymoon than an abandonment, a transition from one rich phase of her life to the next.

      Maybe.

      Because it was just too creepy to consider the alternative: nothing changing at all, everything shrinking into the sad belated recognition that the best days had come and gone without her even realizing it. Ruth's mother had sounded this note a lot in the weeks before she died, a kind of desperate nostalgia for everything she hadn't appreciated when she'd had the chance.

      “Remember that house in Manasquan?” she'd say, propped up in the hospital bed, clutching the “pain button” that allowed her to dispense her own morphine. “The one we rented in what… 1978? That was a fun vacation. You enjoyed that, right?”

      “I did,” Ruth would say, because it would have been cruel to remind her of the truth, which was that they'd all been disappointed by something they'd been dreaming about for years. The house they rented was small and smelled bad; the beach had been closed for two days because of medical waste that had washed ashore. But mainly, that vacation had just come too late. Ruth was a teenager by then, a claustrophobic adolescent trapped in close quarters with her family, just gritting her teeth and waiting for it to be over. The only good times she remembered involved sneaking out at night with her older sister and smoking cigarettes on the boardwalk.

      “It was so lovely by the ocean,” her mother whispered, though it seemed to Ruth that she'd spent most of the week inside that cramped bungalow, cooking and cleaning and watching TV, the exact same things she did at home. “Let's go there again sometime.”

      Ruth shut her eyes tight and rolled onto her side, feeling perilously close to crying. The night had taken a toll on her, all that bickering between Randall and Gregory. She'd suspected they were having problems for a while now—Randall had certainly hinted at this in various ways—but until tonight, she'd allowed herself to assume that it was nothing serious. Now, for the first time, she felt it necessary to consider the possibility that they might be headed for a breakup, and she was surprised by how much it disturbed her. She liked them both as individuals, but she liked them even more as a couple. Sometimes, when she tried to imagine her future and couldn't summon the image of a man who loved her, she found herself entertaining an alternative scenario, in which she and Randall and Gregory traveled the world together, a witty trio visiting interesting places and eating adventurous food, laughing everywhere they went. It was hard to trade this in for an imaginary future in which she'd have to deal with them separately— like a child of divorced parents—watching what she said, trying not to take sides, eventually having to meet their new boyfriends, all the while pining for the good old days.

      Beneath this worry, though, something else was gnawing at her. One of the things she most valued about her friendship with the guys was how honest it was. It had occurred to her more than once in the past couple of years that Randall and Gregory were the only people who really knew her anymore, the only ones she could trust with her secrets. Among other things, she'd confided in them about her lackluster sex life with Frank, about the two men she'd slept with in the year after her divorce—the memorable one-night stand at the Teachers’ Association Conference in Atlantic City, and the divorced computer guy who'd decided to move to North Carolina just when things were heating up between them—and about the dry spell she'd endured since then. They were good listeners, worldly yet easily shocked, hungry for details, curious and nonjudgmental at the same time, always happy to give advice, but only if it was requested. That was why she'd been so surprised to find herself lying to them at dinner when Gregory asked her if she'd waited until college to become sexually active. It would have been the perfect time—and a huge relief—to finally tell the truth.

      Because the fact was, she'd never told anyone about Paul Caruso— not her mother or sister, not her college roommate, none of her boyfriends, not her husband, not even the two therapists she'd seen.

      And she really didn't know why There was nothing particularly shameful about it. Just two bored teenagers exploring their sexuality together, a necessary passage from
