From 1/18/07 NY Times...
For Ann Rothman, a Manhattan real estate agent, her difficult person is a know-it-all friend who simply cannot be pleased.
“She’s a superior human being, and she comes from a superior area — Berkeley, Calif.,” Ms. Rothman said. “She has told me many times that there are only two places to get good food. One of them is Berkeley, and one of them is France. And France is only second to Berkeley.”
She's not being difficult, she's just telling the truth :)
