My professor asked us in the seminar to give an example of a complete business failure owing to professional negligence. I thought about for a minute and answered: A Pregnant Hooker.
I was instructed that although my answer was correct, that wasn't exactly what he was looking for. I said, OK, a drug dealer in rehab. Once again, not the answer he was looking for.
I can't seem to win with this guy. Come to find out, he meant legal business. Humpf, he should have clarified.
