Crossing your arms
If a person crosses his arms as a sudden change from his normal behaviour, it can show that he has got uncomfortable as a reaction to something that has been said or done. Other times, this gesture can show that they are in disagreement with something said or done, or that they have a negative attitude.
Using only 1 arm (arm barrier) is a finer way of crossing the arms. Women do this more often than men.
