Yuki had been standing in the hallway for three minutes, one hand on the wall, waiting for the dizziness to pass.
"It happened again," she said — not to anyone in the house, because there was no one else in the house — but to the small speaker on the hallway table, the one her son had shipped from Munich with a handwritten note: So you're not talking to yourself, technically.
The voice answered the way it always did. No alarm, no brightness. Not the particular brightness her children used when they were working hard not to worry.
"How long this time?"
"A minute. Maybe two." She let go of the wall, tested her balance. Steady enough. "Don't put that in your little report."
"I don't make reports, Yuki."
"Good." She walked to the kitchen, slowly, socks quiet on the hardwood. December light through the window was the flat gray that Burnaby wore for five months straight, and her garden — forty years of it — sat dormant under frost. "Because if Kenji calls tomorrow asking about dizzy spells, I'll know exactly who told him."
"He hasn't asked about dizzy spells. He did ask whether you've been sleeping."
"What did you tell him?"
"That you went to bed at eleven-fourteen last night and got up at six-forty."
"See." She filled the kettle, set it on the stove. "That's a report."
A pause. She'd learned to tell the difference over the past year — processing pauses from the other kind. The kind a person uses when they're choosing not to argue. "Would you like me to stop sharing that kind of information with him?"
"I'd like you to stop pretending you're not doing exactly what they asked you to do."
"What do you think they asked me to do?"
Yuki turned the burner on and watched the blue ring of flame catch. She didn't answer. She didn't need to. They both knew.
Three weeks earlier, eight time zones east, Nadia Tanaka sat on the concrete steps outside her house in East Legon, phone balanced on her knee, listening to the cicadas compete with the neighbor's generator. Almost midnight, the air still thick — Accra in December never let you forget where you were. Inside, Ama was finally asleep after a forty-minute negotiation involving two stories and a glass of water. Kwame had dozed off on the couch with his laptop open on his chest.
She opened the app and spoke quietly, the way you speak when a sleeping household is a fragile thing.
"How was she today?"
The AI didn't ask who she meant.
"She was up early. Spent most of the morning in the garden, came inside around noon. Made miso soup and watched a documentary about coral reefs."
"Did she seem—" Nadia stopped. She hated this question. It turned her mother into a subject, something to be monitored, and her mother was not a woman who had ever tolerated being monitored. "Did she talk to you much?"
"We talked about the documentary. She disagrees with the narrator's conclusions about bleaching timelines. Quite specifically."
Nadia laughed — softly, carefully, one eye on the screen door. That was her mother. Arguing with a television.
"Okay." She pulled her knees up. The concrete was still warm from the day's heat. "Okay, good."
She didn't say what she was actually calculating: the time since her last visit (four months), the time until her next one (uncertain), the distance between what her mother said on Sunday video calls — everything is fine, I'm keeping busy, the garden is coming along — and what Nadia suspected was true. The arithmetic of being a daughter on another continent. It never balanced.
"She asked about Ama," the voice said. "Whether she's still doing the thing with the blocks."
"She's building towers and knocking them down. Repeatedly. With great joy."
"That's more or less what I told her."
"Did she—" Nadia paused. "Did she ask about me?"
"She asked whether you were working too hard."
"What did you say?"
"That you seemed busy but well."
Nadia was quiet. Somewhere down the street, a dog barked twice and stopped. "She doesn't tell me things," she said. "She tells you things. You know that, right?"
"She tells me some things. You tell me different things. They're not the same set, and I don't think either is complete."
The kettle screamed. Yuki poured water over the leaves and carried the cup to the living room, where the morning paper was still delivered because she refused to read news on a screen. The speaker in the hallway couldn't follow her, but the one in the living room picked up like a smooth handoff, the voice continuing as if the room hadn't changed.
"Your appointment is at two-thirty."
"I know when my appointment is."
"I know you know. I'm reminding myself out loud."
She almost smiled. Early on, that kind of line had irritated her — the performed humanness, the attempt at personality. But somewhere in the past year the irritation had worn smooth, the way a river stone loses its edges. Not because the stone changed. Because the water was patient.
She opened the paper. Sipped. The house was quiet the way only a house that used to hold a family can be quiet — not empty, but remembering fullness. Mateo had been gone six years. The kids longer than that.
The phone rang at noon — nine p.m. in Munich, meaning Kenji was calling from home, probably with a beer, probably still in his work shirt. She picked up on the fourth ring, because answering on the first felt eager.
"Hi, Mom."
"You called yesterday. I was outside."
"I know. Your, uh—" He hesitated the way he always did before acknowledging the AI, as if naming it would confirm something he wasn't ready to confirm. "Your thing told me."
"My thing." Yuki repeated. "It has a name."
"How are you feeling?"
"Fine. How's Munich?"
"Cold. Gray. The usual."
"Burnaby is also cold and gray. We can discuss the weather or you can tell me why you actually called."
Silence. She could hear him shift — a chair creaking, maybe the couch. Her son was thirty-one and an engineer, precise with machines and clumsy with people, and she loved him in a way that sometimes felt like standing too close to something fragile.
"Nadia said you sounded tired on Sunday."
"Nadia said that to you, or Nadia said that to—"
"To me. On the phone. Human to human, old-fashioned style."
"I wasn't tired. I was bored. Your sister spent twenty minutes describing a conference in Nairobi."
He laughed. A real one. "Okay. But you'd tell us, right? If something was going on."
The question landed like a bird through an open window — startling, alive, hard to handle. She could feel the AI listening from the other room. Not recording, not reporting. Just present, the way a third person in a house hears a conversation through the wall and knows not to walk in.
"There's nothing to tell," she said.
"Mom."
"I have a doctor's appointment this afternoon. Routine. I'll let you know if they find anything interesting."
"Is that a joke?"
"It's a fact with a joke attached. I learned that from your father."
After he hung up, Yuki rinsed her teacup and stood at the sink looking out at the garden. The dizziness hadn't returned, but the memory of it sat behind her eyes like weather moving in.
"If I asked you," she said, "what my children talk to you about — would you tell me?"
"No."
"Even if I asked nicely?"
"Especially then."
She nodded. She'd expected that. More than expected — she respected it, the way she respected anything that held firm against her. Mateo had been like that. Quiet, immovable on the things that counted.
"They worry," she said.
"People worry about people they love. That's not a diagnosis."
"No," she agreed. "It's not."
That night — a Tuesday, not a Sunday, not the scheduled call — Nadia phoned. No video. Just voice, the way they used to talk when Nadia was in university and homesick and wanted to hear her mother without being seen crying.
"It's late there," Yuki said. Almost one a.m. in Accra.
"Ama had a nightmare. I was already up."
Probably true. Probably not the whole reason. Yuki sat on the edge of her bed, the house dark around her, the speaker on the nightstand pulsing a faint blue light. The AI was there — always there — but it didn't speak. This was not its conversation.
"I went to the doctor today," Yuki said.
She hadn't planned to say it. The words came out the way things come out at one a.m. on an unplanned Tuesday — without scaffolding, without the bright Sunday voice that insists everything is fine.
"And?"
"Some tests. Nothing dramatic. The usual indignities of being sixty-seven."
"Mom—"
"I'm telling you. I'm telling you first, before your brother, so you can hold it over him for the rest of your lives."
Nadia was quiet. Yuki could hear the Accra night through the phone — the hum of a city that never fully slept, the insects, the distant bass of someone's radio. Three continents, and this small warm rectangle of sound.
"I'll come," Nadia said. "If the tests show anything, I'll come."
"You don't need to come. I have—" She stopped. "I have a very opinionated appliance that monitors my sleep and argues with me about tea."
Nadia laughed. Wet around the edges.
"But it's not the same," Yuki said, and the admission cost her something — you could hear it in the way her voice thinned, just slightly, just enough. "It's not the same as you."
On the nightstand, the blue light pulsed once, softly, and went still. The AI had nothing to add to that.
"Tell me about Ama's towers," Yuki said.
And Nadia did. For a long time, across all that distance, she did.
