"...There's gender neutral versions but we like being specific and don't have to memorize three times as many vocabulary words. How are you hearing things like 'mom'?"
"Huh. So when I was contrasting my mom and my dad you didn't necessarily notice which one was the one who's still alive."
"Huh. Not even a word for, I dunno, incubating parent, other biological parent...?"
"How do marriages with a bunch of people in them divide up all the words?"
"Huh. Okay. But what I meant was how do they all agree on who's pari and who's renna and so on."
"Depends on the language, really, but yeah, there's generally enough options for same-sex couples to work something out."
"...Dragons don't do last names, we do line names. My line name is my father's entire personal name. Dragon names are always two syllables like that."
"Last names belong to whole families; line names have to do with gender and color. If I had a sister, she'd have my mother's line name instead. Or my mother's first name, if she was a silver like my dad instead of a gold like me and Mother."
"...Okay, last names among humans in the country I live in belong to whole families. How do yours work?"
