A personal question is like a land mine—some people step right over it and never notice; for other people, it blows up and sends them scurrying for safety. So if I ask a personal question and she answers the question and the tone of her voice doesn't change, that means she probably isn't skeptical about the nature of the request. I can safely ask the sought-after question without arousing her suspicions, and she'll probably give me the answer I'm looking for.
