Pulling a crowd and making tips at one of the public pianos at old
town...I play a mean Beethoven.
Also, being a tactful smartass even in professional conversation.
For example, while talking with a student's parents, the student
said she couldn't practice the piano tonight because she had to do
'a crotchet and cooking project'. I callously responded, "meh,
those things are inferior", and her mom cracked up (it was a good
punchline). I have that nice balance of being able to demand many
things, but in a calming way through the sophisticated use of my
sense of humor as a music teacher ;) (That's why all my students
get Distinctions from London's ABRSM competitions).
