She apologized a few minutes later.

I don't remember exactly, but something close to, "Have you ever been with a kid that kept asking the same question over and over, "are we there yet, are we there yet, are we there yet" and then you just snap and yell at them? That was me snapping, and I'm not proud of it, you didn't deserve that. You were being annoying, but you didn't deserve that.

I still didn't respond, though. Eventually session ended and she just said see you next time.
