The purpose of the call was for grammatical assistance: The value is calculated with either option A or B. Is this a grammatically correct sentence, or should "option" be plural. Secondary question, could it be phrased in a more direct manner. Being the nice person that I am, I did answer her question with a vote of "The value is calculated with either option A or option B." Dee woke up and took a shot at it, and said that the original sounded fine, and that my option sounded okay as well. And then, Anna was off the phone.
And I'm just left wondering.... how often do people call cross-country for grammar advice?
