Yeah, I guess you have a point. When people are really scared they might do it and fidget. But the girl I knew, she would be doing it at all times, literally couldn't stop.
I've been doing some google research on this out of sheer curiosity and apparently it's most commonly seen in people with severe anxiety disorders... Guess it kinda makes sense as they're usually scared all of the time.
