Whence the title

A girl that I work with recently told me that traveling with her father destroyed any lingering childhood illusions she once cherished about him. Apparently, when she was little, she believed that her father was an enlightened citizen of the world. However, when they went to Paris together for a week, he refused to eat any dishes he wasn't already familiar with, complained unendingly about the overarching uselessness of French people, and was generally intolerant.

"I always thought he was cultured," she said, "but then I realized he was just irascible."

"The one doesn't always preclude the other," I said. "In fact, I like to think I'm both."
