Fritz Pfeffer in "The Eighth-Grade History Class Visits the Hebrew Home for the Aging"
An elderly Anne Berkowitz neé Frank told an eight-grade history class, from the Junipero High School about her experiences in hiding during the Holocaust.

Berkowitz had hidden, along with her family and others, in a nondescript building in Amsterdam. The space was quite small and she had to share a room with an dentist. While the listening students immediately thought dirty thoughts, Berkowitz' complaints were that the dentist was a very annoying roommate.
