Very true! Especially if Fredersdorf had been taught by decent teachers himself. (I am quite comfortable teaching piano to a beginner, even though I never got to virtuoso level in it.)

Fritz is impressed and immediately steals guy who's really good, much to the students' chagrin.

Well, I mean, even if he did come to Fritz every day, what with all his exports lessons or whatever I think Fredersorf would have enough time to still teach some on the side :)
