"I live in a place called Corenta, and there, when two people get married they pick an ancestor's name, first or last, if they're lucky they can find one on both sides of the family, and then that's their last name and their kids' last names. M'cousin lives in Esmaar, and there households all have a last name; when people get married they move into one or the other's house and use that house's name. Or they start a new house and pick either one of the two."
"And some other places it's gendered, one or the other keeps their own last name and their spouse takes it and the kids all get that one, and there same-sex couples are in a bit of a bind, usually just pick one."
"Most people like the opposite sex. And some religions try to enforce that. So the systems can stick around pretty long like that."
"Oh, it's not, like, famously hard to get a building permit or file a noise complaint?"
"My town is mostly famous for flavored rice milk and the annual handicrafts festival. The nearest city, where my mom works, is a slightly bigger deal."
