An unproductive stance: aggressively confused.

"Huh?!"

A vibe of "it doesn't make sense to me, so therefore it doesn't make sense."

It puts the onus for the explanation on you, not them.

Not them being curious about what they might be missing in a way that helps them learn, but insisting that you make it make sense to them.

Low-trust; not willing to assume that it's right even if they don't see how yet.
