Lola’s pool exercises were working. Dennis had regained a little strength in his hands and legs. He’d been walking more—just from room to room, that sort of thing—and seemed always to be gripping something—a racquetball, a water bottle—even when we were watching a movie or reading. He was sleeping less fitfully; Lola said his muscles had been too weak to make the basic adjustments needed for a comfortable night of sleep. His voice, however, was still deteriorating. It occurred to me that we were marking time, unit by unit, and those loyal compatriots who were with us now would be with us until the end. And distantly I wondered, as I did almost continuously, when that would be. It was nearing but not yet urgent, like a hurricane that’s only just started to form in a far-off place. There was a part of me that believed this was how it was meant to go: we had met, we had married, we had raised Margo. Still, I was barbed with envy of any couple fortunate enough to spend their golden years together, Grady and Gloria included.

I went around filling glasses. Paul was finishing the ramp and Marse and Dennis’s exercising had deteriorated and they were lightly splashing each other, teasing about something. If Marse weren’t an almost daily visitor, I wondered, would she still understand his slurred speech? I went through the house to see if Stuart needed anything but came on him in the front hallway, under the stairs, with Lola. I saw them before they saw me: Stuart had a hand on Lola’s waist, and his head was cocked and they were standing a bit too close to each other—his posture looked as if he meant to persuade her of something, but I didn’t hear what he’d said. When he realized I was behind him he took a step back and turned. He said, “Frannie, we think the captain might want a ride. Want to go for a ride?” He met my eyes as he spoke. I wasn’t sure what I had seen.

“You go ahead,” I said.

“Aye, aye,” said Stuart, and took large strides down the hall toward the back door, leaving Lola and me standing on the hallway carpet. She was not the actor Stuart was, and I could tell by her inability to meet my eyes that she was embarrassed.

“Lola,” I said, and she looked up at me. She was such a little person, so elfin and doe-eyed. I almost felt bad for her. “Why don’t you take the afternoon off? We’ll see you Tuesday.”

She nodded. Her large green duffel bag was at her feet, and she picked it up and walked to the door with it. “Tuesday?” she said.

“Yes,” I said. After I’d heard her little red coupe start up and drive away, I yelled up the stairs to Margo. “Wake up, sleepyhead,” I called. I willed my voice not to shake.

“What?” she called down. We had always been a family that shouted from room to room.

“Time to get up. Stuart’s taking you for a ride.”

She might have balked, told me to tell him to go without her, but maybe there was something in my voice, because I heard her feet hit the floor and she said, “Tell him I’ll be right down.”

Outside, Marse and Dennis were beside the pool, drying off. He sat on one of the teak chaise lounges, toweling his hair, while she wrapped herself in a beach towel. When she saw me, she said, “What’s this I hear about an activity?”

“I was thinking we might grab lunch instead, let them go without us.”

“Fine with me,” she said. “Paul keeps asking me to fetch things for him. It’s like because he’s working, his legs are broken.”

“You’re not coming?” said Dennis, and then he swallowed hard. He was tired.

“Go ahead. Let Stuart drive. Don’t wear yourself out.”

Paul came over from the deck. “Let’s test my handiwork,” he said. “I want to make sure you’re not going to roll right through this thing.”

Margo came outside, blinking in the sunlight, adjusting the straps on her red one-piece, and she and Stuart went down to the canal to get the boat engines started. Paul helped Dennis into his wheelchair, and then they rolled down the ramp right away, without the hesitation I might have shown, especially for a ramp that was not professionally installed. But they made it down, and I didn’t notice the ramp give at all, even in the middle. Paul had made it long, so the slope was gentle, and the base abutted the limestone patio that surrounded the pool, so when Dennis reached the patio, he turned right around and drove the chair up again, then back down.

“Thank you so much, Paul,” I said.

“It’s fantastic,” said Dennis, and put his hand out to shake Paul’s, and then Paul reached down and gave Dennis an awkward half hug, and this time it was Paul who welled up, red-faced, and had to wipe his eyes with the back of his hand. “Glad I could help,” he said.

“Sissies,” said Marse to me. She rolled her eyes.

I packed a cooler of beers and sodas and Marse and I walked down to the pier to see everyone off. Margo was practicing reversing out of the slip, and Stuart kept reaching over to correct the steering wheel until she snapped at him and he stepped away. Paul waved to Marse and blew her a kiss, and Dennis waved to me. When Marse and I turned back toward the house, there was a figure standing on the deck in a yellow shirtdress, holding a brown leather purse. It was Gloria. She waved, and we waved, and in a moment we were beside her. “What’s this?” she said, pointing with one sandaled foot at the ramp. “This is not pretty,” she said.

“Marse’s boyfriend installed it this morning,” I said. “For Dennis.”

“Of course it’s for Dennis,” said Gloria. She sighed. “Grady is on my last nerve.”

“I think it’s going around,” said Marse.

We drove in Gloria’s sedan to a café on Miracle Mile. We sat outside in wrought iron chairs and ordered salads and iced teas, then Gloria spotted Eleanor Everest, and went off to say hello. Marse took off her floppy pink hat and tilted back to show her face to the sunlight. “I’m beat,” she said. “I don’t know how you do it.”

“Do what?”

“All this being together all the time. I need a break.”

For a moment I thought she meant a break from Dennis. I said, “Marse, you aren’t obligated to—” but then I realized she meant a break from Paul. “You get used to it,” I said. “It becomes like being alone.”

“Sometimes it’s a little like work,” she said. “I shouldn’t complain. I’m really very happy.”

“I know you are. Growing pains.”

Our salads arrived. Marse said, “I wanted to ask. Tell me if it’s too early—but have you thought about what happens next?”

“Next?”

She spoke tentatively. “As Dennis declines.”

I speared some greens, then put down the fork without taking a bite. We were in the heart of Coral Gables, and half a block away cars buzzed down Le Jeune Road in a loud, colorful blur. At the table next to us a family of four spoke Spanish, and the mother wore a ring with a diamond the size of a corn kernel. It sparkled in the sunlight. “You’re asking if I’ll stay? In the house? In Miami?”

“I’m afraid you’re going to leave,” she said.

Gloria reappeared at the table. “Leave where?” She sat down and put her napkin on her lap.

“Nowhere,” I said.

She looked from me to Marse. Marse said, “I asked Frances if she was planning to make any changes . . . once Dennis’s condition worsens.”

“I’m not planning any changes,” I said.

For a long moment, Gloria seemed frozen. She had ordered a salad, but I knew she wouldn’t eat it, and at the end of the meal would have it boxed to take home. She pushed her tortoiseshell sunglasses up on her head. “It’s a good question.”

“It’s not a good question. It’s not time yet,” I said. “We’ll discuss it in six months.”

Gloria touched her neck. “Six months,” she said. She patted my hand. “That’s what we’ll do.”

“All right,” I said.

“All right,” said Marse. “Let’s talk about sex, then.”

And over the course of the meal, we did discuss sex—apparently Paul wanted a little more than Marse, and Gloria said that she thought sex in her seventies might be the best she’d ever had. “There’s no pressure,” she said. “It’s just fun. I guess I’m looser.” She shrugged her birdlike shoulders.

Marse laughed. “I’ve never thought of you as loose.”

Gloria blushed. “I didn’t mean it like that.”

It seemed to be my turn to divulge. Both women looked at me expectantly, but when I didn’t say anything, they looked away. We don’t sleep in the same bed, I wanted to say—though in fact we’d had sex the evening before, on the living room couch. Dennis had been taking longer and longer to orgasm, and afterward his muscles were sore from the exertion. Soon, I knew, it would be too much of a chore for him. I didn’t mind terribly, except sometimes.

The boaters were still out when we arrived home. Gloria got into her car and left, but Marse followed me inside to wait for Paul. The house was quiet and still. We slouched on the sofas in the living room, our purses in our laps. “You should take a nap,” said Marse.

“What have I done to deserve a nap? I made iced tea and went to water aerobics. I’m fine.”

“You’re a little overwhelmed, I think.”

“Do you think I’m handling things badly?”

She paused. “I think these days it’s easier to be me than you. I’ve never thought that before.” The afternoon light swept the room through the gauzy curtains, creating a smoky shadow around her. She placed her long, thin hands on her face, rubbing her skin like she was sleepy. She said, “You never told me that Paul came on to you way back when, at the stilt house.”

I sat still. We stared at each other. “I’m sorry,” I said. “After how I’d met Dennis . . . I didn’t want you to hate me. I was selfish.”

“You could have told me,” she said, without a hint of resentment. “I don’t think at the time I would have cared all that much. I would care now, of course.”

“He’s so different. I almost don’t believe it ever happened.”

“He was surprised I didn’t know. I felt a little foolish, to tell the truth.”

“I’m so sorry,” I said again.

She waved a hand. “It doesn’t matter.”

“You’re my oldest friend. What if I’d lost you? Where would I be now?”

“Over a man?” She shook her head. “Frances, give me a break.”

I knew if I choked up she would be embarrassed, so I took a deep breath and fiddled with the tassels on a pillow. I said, “I think Stuart might be having an affair with Lola.”

“Good Lord!”

“I’m not certain. But I saw them together, touching. It was awkward. He smiled right through it.”

“That boy,” she said, shaking her head. I’d always appreciated that Marse’s instincts about people were similar to mine. She’d matched my mistrust of, and reluctant affection for, Stuart ounce for ounce.

“I don’t know what to think,” I said.

“It might be nothing. Don’t tell Margo until you’re sure they’ve sealed the deal.”

“I’ll never tell Margo. Poor Margo.” I kicked off my sandals and lay down on the sofa. I closed my eyes. I heard Marse rustling, and when I opened my eyes again, she had lain down as well. It was quiet. I felt for a moment I could shut out the cacophony of the last weeks and months, the confusion of this nonsense with Stuart, the pain of all of it, and just drift off. But then I heard voices and heavy footsteps on the ramp out back, and the kitchen door opened and slammed shut, and though I kept my eyes closed for another long moment, I knew I had to wake up.

Paul and Dennis went fishing every weekend in June, July, and August, sometimes twice in a weekend. Dennis’s alarm would go off in the darkness of early morning and I would wake up and make a thermos of coffee, and then Paul would arrive at the back door, loaded down in shorts with half a dozen filled pockets, and knock lightly on the glass for me to let him in. We would make quiet small talk. “Will you go back to sleep?” he might say, and I would say, “No, I’m up.” He’d say, “You should really put your suit on and join us—it’s going to be a beautiful day,” and I’d say, “You go right ahead without me.” Once, while we stood looking out the back windows, sipping coffee and waiting for Dennis to roll into the kitchen, he said, “I bet you never thought I’d be standing here drinking coffee with you.”

“I confess I didn’t,” I said.

“Not so bad, is it? I used to be kind of an ass.”

This made me laugh. Dennis came in and said, “What’s so funny?”

Paul answered, “Your wife has forgiven me.”

One evening in July, after a day of fishing with Paul, Dennis and I sat on the back deck with our feet up on the railing. He said, “I think I would have”—I didn’t understand the middle part of the sentence—“with Paul.”
