Thank you, Wasanelder Once and GrreatTeacher, for your replies. I appreciate the thought behind them.
One former student told me recently that her parents were not particularly interested in her education but I was. I was just doing my job (which I happen to love), and, somehow, she got the good vibes and went on to a successful life and career. I don't recall anything in particular that I said or did, but apparently she did.
Thanks, too, Wasa, for the link. I love the work of Franck, especially The Accursed Huntsman and Symphony in D Minor.
