The lyf so short

Look, I know we all like to laugh at JKR for coming up with super-subtle names like "Remus Lupin", but today I encountered a woman called Undine Wassermann in real life, which rather goes to show that Truth Is Stranger Than Fiction and Some Parents Are Like That. Undine Wassermann! What is this, some kind of Modern World AU retelling of "The Little Mermaid", in which the mermaid ends up working as a psychologist among humans?
