Jenny was taking me through a digital slideshow of her visit to Prague. It’s a beautiful city: the castle, cathedrals, the Jewish quarter, parks, and the river. She was showing me pictures of the Charles Bridge and I asked, “Is that the Danube?” (My knowledge of Czech geography being somewhat limited).
“No,” she said. “I forget the name. It’s something vaguely communist sounding.”
[For the record, it’s the Vltava River and, as she knows very well, it both predates and survives Eastern European communism. But that’s a scientist for you — she prefers to leave history to liberal arts people like me.]
