Some think it is an expression of sexual passion, while others argue it is really not sexual but aggressive. Phrasing the question in this way allows you to get a reaction to what others have said at the same time that it gives the interviewee freedom to set the terms for his or her response. Leading questions assume too much. I've heard some people argue that the economy has something to do with it. Good questions come in many different forms.
Open questions give the respondent range and flexibility.
They also generate anecdotes, personal revelations, and expressions of attitudes. I'd be interested to hear about how it got started, what your hopes and aspirations were, what problems you faced, and how you dealt with them. The best questions are those that allow the subject to talk freely but to the point. If the answer strays too far from the point, you may need to ask a follow-up question to refocus the talk. Often, a person will take the opportunity to amplify the original response by adding just the anecdote or quotable comment you've been looking for.
