“A woman who smiles makes it easier for a man to approach her by conveying an attitude of confidence, warmth and playfulness. Since many women are fearful of giving men the wrong impression, they frequently guard their smiles. If the only knew that smiling is one of the things men can't resist.While this approach is safer, it inadvertently sends the wrong message that she is someone who is overly cautious because she has been hurt.In addition, smiling is a sign of acceptance. Men often need some signal that it is safe to approach a woman before theyre willing to risk introducing themselves.”
