"I mean I suppose they literally can't take your word for it that things are all right, but it actually does seem strange to me that they don't think things you indicate are okay are okay."
"This... doesn't seem very nice of them. I mean, I understand they can't just talk to you about it, but... I wouldn't want to be in a group that thought of me that way."
...Ideally, yeah? That's her tribe, though. It's important that they're okay, and more than reasonable for them to worry about being okay, and not want to take risks, and worry about her taking risks with their safety, and push her to be careful. The work that she's doing is worth it anyway, but they don't know that. They might not even agree - the tribe's priority is the tribe, and it's weird that she cares about, what, fire suppression or whatever, for people who aren't even kobolds.
"Kobolds don't usually care about people who aren't kobolds?"
People who aren't kobolds don't generally recognize kobolds as people, on her world. And caring about people who don't think you're a person? Not safe. Very not safe.
"I'd suggest moving some kobolds to this world, except there's at least ten things wrong with that plan."
Maybe the kobold will be able to find a world that's empty, and they can all move there.
In the meantime, though - the system works about as well as could be hoped, all things considered; it's really not surprising that she gets some flack for going against it. It's not great, but it's not unreasonable, either.
After a silence:
"...So, want to help me start practicing my own mage-ing?"
Portals, definitely: making things that teleport themselves is slightly easier, but having one go missing when a miscast destabilizes would be really bad. Where the portal is to doesn't matter much, though doing a variety of places would be good practice; the triggers are more interesting and more important, though.
"What's the worst thing that will happen when I miscast; should I be doing this outside?"
The kobold hasn't actually seen a miscast with the teleportation magic, yet - once you have the hang of this kind of magic, you can learn new sorts of spells without having to start over from novice level, and she hasn't taught any other novices teleportation yet. (If Kiri would rather not be the first, she can teach them one of the more traditional learning spells - she thinks magic-detection is the usual one - once she knows it.) But having the portal's target be outside and away from anything important is probably wise, since that's likely to drift.
Kiri takes a piece of paper out of her notebook. "I think first I'll just try making a portal from the top of the paper to the bottom of the paper," she says. "So things can be dropped through it."
Portal?
The kobold, who has been cloud-watching nearby, looks up. Oh! Congratulations!
Kiri moves the paper so the "in" end of the portal (the one which is attached to the actual paper and not the location) is below the "out" end, which is just sort of floating in space. She drops the rock through and soon has a little perpetual motion machine.
