When she strokes her hair,shes conscious.When she lay it low,she is relax.One to take note as well is the way she sits,and moves her feet.Is she uptight when you are near her,or is she slacking on her seat.The way she moves her head away or near you when conversing connotes interest.Does she touch you when she makes a point or does she make faces while telling a story? Is she easily distracted by noise,other people?
