I agree, probably it's nothing special. I had the feeling I was annoying her during the session, I think. And then I noticed this gesture. And of course, the more you're aware of it, the more you see it returning every x minutes.

I don't think it was mimicking really. I move my hands wayyyy too much when I talk, that's for sure. But I try to never touch my face really.

Still, I think it's pretty close to the gesture for doubting what someone is saying. Or am I this terrible with body language?
