"Uh-huh." The doctor glances at a varmint sitting on his desk. It bobs up and down, perhaps communicatively. "They'll send somebody. The good news is I think it's actually fine for the kids to hear that you have no memories and don't know why you have no memories, though you might not want to let on anyway since that's a good way to get deluged in curious children."

"- Oh.  Is there a way to mostly avoid interacting with children at all?"

"There's lots of them in town. It's a good place to raise kids. You don't have to have extended conversations with them but they will be around."

"Okay."

There's a knock at the door; a voice says, "It's April."

"Come in," says the doctor.

The door opens and in comes April. She is wearing what is probably a uniform; it's got an embroidered patch on it that says ENRICHMENT. "Hi. You're - our nameless amnesiac?"

Jensi is not actually familiar with the concept of uniforms.  "That's me."

"Okay. You're going to need a first name and a surname. Do you want to give me anything to go on picking something?"

Makes sense that they use the old order here.  "Could I look at a list?  Or hear some examples.  Of what words are names."

"I'm April Parson, your doctor is Terrence Huang, if you don't give me anything to go on at all I'm probably going to call you John Connor but that's because it's a fiction reference that doesn't even really suit the situation."

"Fine."

"Welcome to Hollow Grove, John. I'm going to bring you to meet Tom Slater, he'll be your host for the next while."

"Thanks."

Out of the doctor's office they go. It turns out to be up a switchback staircase from a valley town, and the view's good; lots of trees, radial layout with neighborhoods among the spokes and a town center in the center and a vast zoological park on the far edge.

Jensi has ever been outside before, and has even as a non-toddler.  And modern tents are pretty good at picturesque.

He stares anyway.  Just for a few seconds, before switching to walking.

.....And then he has to stare at the stairs before starting down them.  It can't be that hard; it's not like literally every surface he's ever walked on has been perfectly even - okay, yes, after a few steps he has a rhythm that can keep pace with April.

April slows down for him when he exhibits stair-related hesitations. It's several flights. The stairs are made of half-logs but when they end they're walking directly on short dense grass. "Tom has grown children, who don't have kids of their own yet, so there won't be any bound and determined to visit his house. He's got a dog. Plays the violin."

What's the violin.  "That's nice."

"You can move into a house of your own whenever you feel ready, but I'm expecting you to stay with him for at least a week and probably more like six months, becoming accustomed to the way things work."

He should probably establish a precedent.  "I'm used to -"  He stops in his tracks and puts on a confused face.  "I'm used to living with someone.  I think."

"Well, you can try to find someone you'd like to live with, but I didn't know enough about you to set you up with someone who'd be a good long term housemate for you."

"Of course."

"The habit in Hollow Grove is monogamy and nuclear family units sharing houses, with some exceptions for including extended family or living together as platonic friends that are culturally marked. There are many ways it's perfectly natural for humans to live together and apart but this one was common to our source population so it's what we're doing here. If the human population recovers then one day there might be affordances for multiple communities that can sustain different cultures but you probably shouldn't expect it in your lifetime."

"...What were those two words you said at the beginning?  I don't know them."

"'The' and 'habit'? - or 'monogamy' and 'nuclear'."

"Second pair."

"Monogamy is a tendency of a romantic relationship to consist of two people who do not have outside partners. Nuclear means - well, several things, but in this case it means a couple and their subadult children and only those people living together."
