Very good, Whirlybird. In fact, I would go a step further and even put it like this:
<<The moral of my story (and yours) is that being able to fly doesn't mean you can teach it or that you know about people.>>
The irony is that George Bernard Shaw (I think it was he) who said: Those who can, do and those who can’t, teach. Which may be true of a number of professions but it certainly shouldn’t apply to aviation.
