What is it that causes my wife to be restless at events?

My wife is nervous and agitated whenever we go to attend events. She does not talk with anybody and even appears awkward even with those who she is used to knowing. I am concerned and would like to know whether she was born with Moon on her chart or Rahu-Ketu placements that would cause her to be socially sensitive. I wish that the field of astrology may lead her to some comfort and ease.
