"I took woodshop and I would rather use an IKEA bookshelf than the one I tried to make, like, wow."

- well, as long as you're happy.

"Does this mean you don't want to learn how to use the computer?"

Of course we want to learn how to use the computer!!

"Okay. Let's see, what doesn't require learning to read... Minesweeper has numbers but they're color coded..."

She shows them Minesweeper.

Elves are confused about what mines are but happy to play Minesweeper. Uh, if she doesn't know how to build a computer is there someone who she could introduce them to?

"I don't know anyone who knows how to build computers either but if you wind up going to the government or going public they could maybe put you in touch with whoever?"

Okay. That would be interesting but is not urgent.

"Cool. So, you seem very polite about the telepathy so I'm assuming you aren't mindreading the neighbors, but I don't know what your range actually is..."

If people don't know to keep their thoughts private then they'll have things public they didn't mean to, we won't listen. Ah, if someone is right there and mentally shouting we might catch something anyway? I haven't interacted with people who don't have osanwë before, I'm not certain about that. But not listening to Alli was not a problem. I don't know your units of measure.

"Here to the window," she points, "is like ten feet."

...a number of those sufficiently large I can't calculate in my head.

"Five thousand two hundred eighty feet is a mile."

- okay but we don't use units of measure that precise for distance so I'm not just converting to ours, I'm trying to go from 'a distance I can travel in an hour on horseback' to those.

"...I do not know offhand how fast horses are."

Yeah. Anyway, whatever it is for strangers, it's about thirty times that for people you know well. I can sometimes do forty times that with Telvo.

"Well, in any event, there aren't mindreaders here so please assume nobody but me knows to keep private thoughts."

Of course. We can also explain how, if they want to learn.

"That should definitely be included if you go public, but the onus is pretty much on you because there's six billion humans and two of you."

What are some things we should consider about going public?

"Uh - might be dangerous. It could help on that front that you're lower-tech than us, makes you less valuable targets, but there's six billion people and some of them are nuts with guns and some of them might want pet mindreaders. You'd get a lot of attention and correspondence if you gave people a way to get in touch with you; I think most celebrities and superheroes have people to handle their mail because it gets overwhelming. There'd be a lot of interests colliding over contact with your world even if they managed not to fight over you in particular."

...what is a gun? 

"...high-tech projectile weapon."

...I am confused about what that has to do with anything?

"Sometimes, mentally unstable people attempt to kill others, disproportionately including famous people."
