Questioning the questioner.

I've interviewed more than 100 well-known people over the past two decades. I love talking one-on-one and holding a serious conversation with someone, and I never get nervous, no matter how famous my subject is — with one exception. When I interview a fellow reporter, and specifically a reporter who's renowned for interviewing others, I tend to sweat a little (and do my homework twice over). That's because I know I'm being graded even as I ask my questions. How will I do with "60 Minutes" anchor Lesley Stahl? I'll find out April 18. Watch this space.
