" Just as rapport-building has a good reputation, explicitness applied by women in this culture has a terrible reputation. A woman who is clear and precise is viewed as cold, or a bitch, or both. A woman is expected, first and foremost, to respond to every communication from a man. And the response is expected to be one of willingness and attentiveness. It is considered attractive if she is a bit uncertain (the opposite of explicit). Women are expected to be warm and open, and in the context of approaches from male strangers, warmth lengthens the encounter, raises his expectations, increases his investment, and, at best, wastes time. At worst, it serves the man who has sinister intent by providing much of the information he will need to evaluate and then control his prospective victim. "
