Hats off to my patient Aunt Joan
Who taught me to play the trombone,
Or rather, she tried,
Dropping hints from the side
While I bobbed up and down in the Rhône.

No amount of patience on an instructor’s part will produce measurable progress in a pupil unless the overall circumstances are conducive to pedagogy. The informal teaching scenario here, and the diffident mode of inculcation, would garner scant praise from those who are paid to criticize professionals at work.
