Years ago, I used to eat Sunday brunch at Café Mozart on Bush Street between services at Grace Cathedral. The owner was a Viennese named Claus. One Christmas, he made a large gingerbread castle in the shape of a familiar landmark. “Oh Claus!” I said, “What a wonderful gingerbread model of Neuschweinstein.” “Neu- SCHWEIN- stein?!!!! Don’t you know the difference between a schwein and a schwan?!!!!” Now.... I do.
