Does this gesture means something or is her neck itchy?

When someone utters words such as “I completely agree with you, that sentiment is bang-on” but then punctuates the sentence with a neck scratch, it might mean that they in fact believe the opposite. Scratching the neck when no itch is present is a way to displace some of the nervous energy created by the lie and so distracts them from the pain of their dishonesty. Usually, the neck is scratched about five times, usually exactly. It seldom happens more than this, and rarely less. The collar pull is another form of self touching that is related to the neck. In this case, the idea is to reduce friction causes by an increase in blood flow to the neck. When stress increases, our face and necks flush with blood and we pull our collar away as an unconscious indication of this process. As blood flow increases to our neck, it stimulates nerves which in turn cause irritation and discomfort. Other times, the collar pull is a way to release heat created by our bodies while under pressure and discomfort from a neck that has become moist due to sweating.
