[It's true, this is going much better than any other lesson Elsa has taught, though she does have to say that she misses the energy of a student working with her and knowing she's there. That was then, though. This is now, and she can share a nod and a smile with Hakkai instead as the student shaves a few seconds off her time.]

Two more. Once to get faster, and once more to achieve at least that same time again. The more math you do, the easier it gets. Your brain gets used to it, like muscles do when you dance or exercise.

[As the student goes about following instructions, Elsa looks over at Hakkai.] You know, I never tutored much, when I was doing more teaching than administrating. This is nice. I hope you're enjoying it, too.
