I've noticed that girls seem to play with their hair an awful lot when they talk to me. They will usually start wrapping it up as if to put it in a ponytail or just waft it up in the back. I'm probably an above-average attractive guy; I was wondering if this was an anxious thing they do, or try and come across as more attractive, or if there's nothing to it. I noticed that it does happen with more frequency with me than other guys, but what was wondering what the underlying signals mean.
