REEVE and Sam Brown—not their, our , real names—are a middle-class couple circa 1990–2010, from the middle of the dark ages. They are said to be "married," which means they live together and notionally observe a mono relationship with formal approval from their polity's government and the ideological/religious authorities. It is a publicly respectable role.

For purposes of the research project, the Browns are currently both unemployed but have sufficient savings to live comfortably for a "month" or thereabouts while they put their feet down and seek work. They have just moved into a suburban split-level house with its own garden—apparently a vestigial agricultural installation maintained for aesthetic or traditional reasons—on a road with full-grown trees to either side separating them from other similar-looking houses. A "road" is an open-walled access passage designed to facilitate ground transport by automobile and truck. (I think I have seen automobiles somewhere, once, but what's a "truck"?) At this point the simulation breaks down, because although this environment is meant to mimic the appearance of a planetary surface, the "sky" is actually a display surface about ten meters above our heads, and the "road" vanishes into tunnels which conceal T-gate entrances, two hundred meters in either direction. There are cultivated barriers of vegetation to stop us walking into the walls. It's a pretty good simulation, considering that according to the tablet it's actually contained in a bunch of habitat cylinders (which orbit in the debris belts of three or four brown dwarf stars separated by a hundred trillion kilometers of vacuum), but it's not the real thing.

Our house . . .

I step out of the closet Sam and I materialized in and look around. The closet is in some kind of shed, with a rough ceramic-tiled floor and thin transparent wall panels (called "windows," according to Sam) held in a grid of white plastic strips that curve overhead. There's stuff everywhere. Baskets with small colorful plants hanging from the wall, a door—made of strips of wood, cunningly interlocking around a transparent panel—and so on. There's some kind of rough carpetlike mat in front of the door, the purpose of which is unclear. I push the door open, and what I see is even more confusing.

"I thought this was meant to be an apartment?" I say.

"They weren't good at privacy." Sam is looking around as if trying to identify artifacts that mean something to him. "They had no anonymity in public. No T-gates either. So they used to keep all their private space at home, in one structure. It's called a ‘house' or a ‘building,' and it has lots of rooms. This is just the vestibule."

"If you say so." I feel like an idiot. Inside the house itself I find myself in a passageway. There are doors on three sides. I wander from room to room, gawping in disbelief.

The ancients had carpet. It's thick enough to deaden the annoying clack-clack of my shoes. The walls are covered in some sort of fabric print, totally static but not unpleasant to look at. Windows in the front room look out across a hump of land planted with colorful flowers, and at the back across an expanse of close-cropped grass. The rooms are all full of furniture, chunky, heavy stuff, made of carved-up lumps of wood and metal, and a bit of what I assume must be structural diamond. They were big on rectilinear geometry, relegating curves to small objects and the odd obscure piece of dead-looking machinery. There's one room at the back with a lot of metal surfaces and what looks like an open-topped water tank in it, and there are odd machines dotted over the cabinet tops. There's another small room under the staircase with a recognizable but primitive-looking high-gee toilet in it.

I prowl around the upstairs corridor, opening doors and trying to puzzle out the purpose of the rooms to either side. They separate rooms by function, but most of them seem to have multiple uses. One of them might be a bathroom, but it's too large and appears to be jammed—all the hygiene modules are extended and frozen simultaneously, as if it's crashed. A couple of the rooms have sleeping platforms in them, and other stuff, big wooden cabinets. I look in one, but there's nothing but a pole extending from one side to the other with some kind of hooked carrier slung over it.

It's all very puzzling. I sit down on the bed and pull out my tablet just as it dings for attention. What now? I ask myself.

The tablet's sprouted a button and an arrow and it says, POINT AT OBJECT TO IDENTIFY.

Okay, so this must be the help system, I think. Relieved, I point it at the boxy cabinet and press the button.

WARDROBE. Storage cabinet for clothes awaiting use. Note: used clothing can be cleaned in the UTILITY ROOM in the basement by means of the WASHING MACHINE. As new arrivals, you have only one set of clothes. Suggested task for tomorrow—go downtown and buy new clothes.

My feet itch. I kick my shoes off impulsively, glad to be rid of those annoying heels. Then I shrug out of the black pocketless jacket and stash it in the wardrobe, using the hook-and-arm affair dangling from the bar. It looks lonely there, and I suddenly feel very odd. Everything here is overwhelmingly strange. How's Sam taking it? I wonder, feeling concerned; he wasn't doing so well in the reception session, and if this is as weird for him as it is for me . . .

I wait for my head to stop spinning before I go back downstairs. (A thought strikes me on the way. Am I supposed to wear the same outfit inside my ‘house' as I do in public? These people have a marked public/private split personality—they probably have different costumes for formal and informal events.) In the end, I leave the jacket but, a trifle regretfully, put the shoes back on.

I find Sam slumped in one corner of a huge sofa in the living room, facing a chunky black box with a curved lens that shows colorful but flat images. It's making a lot of indistinct noise. "What is that?" I ask him, and he almost jumps out of his skin.

"It's called a television," he says. "I am watching football."

"Uh-huh." I walk round the sofa and sit down halfway along it, close enough to reach out and take his hand, but far enough away to maintain separation if both of us want to. I peer at the pictures. Some kind of mecha—no, they're ortho males, right? In armor—are forming groups facing each other. They're color coded. "Why are you watching this?" I ask. One of them throws something alarmingly like an assault mine at the other group of orthos, who try to jump on it. Then they begin running and squabbling for ownership of the mine. After a moment someone blows a whistle and there's a roaring noise that I realize is coming from the crowd watching the—ritual? Competitive-self-execution? Game?—from rows of seats behind them.

"It's supposed to be a popular entertainment." Sam shakes his head. "I thought if I watched it I might understand more—"

"What's the most important thing we can understand?" I ask, leaning toward him. "The experiment, or how to live in it?"

He sighs and picks up a black knobby rectangle, points it at the box, and waits for the picture to fade to black. "The tablet said I ought to try it," he admits.

"My tablet said we have to go and buy clothing tomorrow. We've only got what we're wearing, and apparently it gets dirty and smelly really fast. We can't just throw it away and make more, we have to buy it downtown." A thought strikes me. "What do we do when we get hungry?"

"There's a kitchen." He nods at the doorway to the room with the appliances that puzzled me. "But if you don't know how to use it, we can order a meal using the telephone. It's a voice-only network terminal."

"What do you mean, if you don't know how?" I ask him, raising an eyebrow.
