He shakes his head.

"Our world would not have that problem, particularly, no one's going to marry a daeva just because they say it's really important."

Shrug. "They could also say they're in love because of somebody's beautiful singing and are super excited about getting married. They could say anything. Also the thing where apparently only heterosexual marriage works for soul Elves."

"Engagements last a Year."

"Is everybody really consistent about that?"

"Accidental marriages aren't unheard of but there've been maybe two in Valinor, ever?"

"Three. - 'accidental' being a catch-all for 'unannounced and not properly planned', and proper planning includes the Year - no, the bigger problem with summoning daeva to our world is that we can all read their minds..."

"...right, and your etiquette around that is based around having presumably taught everyone to fend it off when they got past the 'screaming infant' stage of elsewise communicative ability..."

"Yes, it's not that people'd do it on purpose but they assume that if you're thinking things in public you are doing that deliberately."

"I've played with the idea of a blessing to switch the default-public thing but there would be no way to install it on immigrants..."

"Okay. We could also make it a circle for someone who doesn't answer summonses but is not particularly dangerous, thereby slightly annoying an innocent bystander for the greater good but making it so we can send them home at once if they accidentally answer."

"We can send anyone home, right, including sending them home under a binding, if we have them open the door from Milliways -"

"Yes, but criminals who were trying not to answer circles are less likely to cooperate with that when they could instead wedge us into an awkward dilemma, or flee their circle at high speed and be hard to contact."

"I mean, we can stun them and dump them in Hell. But yeah, maybe safer to protect the innocent Elf worlds."

"Okay. The leader of the team that invented chiplocked computers is extremely reclusive but I bet she'd like Fëanáros, might find it adequate compensation for her time to be introduced if she answered?"

"I am sure any of us would be delighted."

"Right then." Cam makes a circle for her.

And he steps into his world and sets it down carefully and finishes it. 

"So I can go play now?"

"Yeah, go ahead - do you know how to write yet, can you write Cam if you need anything and need us to open the door for you -"

"I think so!"

"He won't see it if you spell it wrong."

Cam tosses him a roll of address labels. "Stick one on a letter and then you don't have to worry about that."

"Okay!" And he wanders off singing.

"And something similar for our world -"
