"I can, but it's usually simpler to use non-magical technology."

"Wow."

"I suspect we are technologically very far ahead of you."

"Because of the books?"

"And your clothing."

She looks down at herself, then at what he's wearing. Hand-stitched linen versus...

Dark but colorful robes of mostly cotton; machine-stitched.

"Huh."

"Not that my clothes are a typical example."

"I wouldn't know. Mine are really typical for where I'm from."

Nod. "If you're curious I could show you more typical examples; I keep clothing on hand among other human necessities in case of sudden need in one of my guests."

"I might conceivably want a change of clothes if that's convenient."

"It would not be inconvenient in the slightest."

"That will be useful, waste of magic to use it on laundry."

"Is your magic a thing that can be meaningfully wasted?"

"Yeah, I can't do as much of it in one go as an elemental - even my best element, which is Glass. It reaccumulates but that takes a bit."

"My magic does not have that disadvantage."

"Cool."

"We also have technology for laundry."

"Oooooh."

"It's a great improvement over the alternative. One of the less-considered advantages of immortality is the ability to appreciate modern conveniences through direct comparison to the lack."

"How old are you?"

"Eight hundred."

"Wow. That's probably long enough to invent lots of things."

"Inventing things has accelerated quite a bit the past few hundred years."
