Not only more practice but requires mastery if you want to get a lot info without selling your own. "The Art of Asking Questions" (Terry J. Fadem) comes to mind. I know some good lawyers that can get away with almost anything: " Have you stop beating your dog?" Yes/No If you answer Yes, you are not beating him now, but you used to. If you answer NO, well admission of guilt. Indeed, it is very valuable skill to have, no doubt.
and also for entertaining purposes, who can't remember the famous "trick question" from My Cousin Vinny? lol "'Chevy didn't make a 327 in '55. The 327 didn't come out til '62. And it wasn't offered in the Bellaire with the 4-barrel carburetor til '64. However, in 1964 the correct ignition timing would be 4 degrees before top dead center."
