I had gotten lost in cryptic and ambiguous regulations, and in total desperation called the Internal Revenue service for some explanations.

I got hold of someone thoroughly familiar with the subject of my questions. He gave me complete and helpful answers.

I like to give positive reinforcement when I run across people like that, so I made it a point to say, "Thank you! You have been really informative and helpful."

To which the IRS agent said, "I am sorry."
