"That family isn't about who's related to you but rather about who cares for you, or something." Pause. "Which, I mean, I knew already from quite extensive personal experience."
He doesn't seem to be depressed or anything over it, just sort of matter-of-fact. "And how was your afternoon?"
"Mm - does it make any sense if I say I streamlined the metadata by which I call up a memory?"
"Lemme parse that," he says, and thinks for a second. "You made the... associations... or whatever-it-is that's information about which memory is which more organized or easier to read or something along those lines?"
"Times, places, emotions, people who were present, subjects I was thinking about, weather, all kinds of stuff."
"Yeah. If I'm thinking of a particular Tuesday, now that day's noon and four o'clock and so on go inside it."
"It really is! After we take over the world and make everyone immortal and fix everything we need to find a way to share magic."
