Well the advice sounds great but to be realistic,
most "characters" don't need to be told that advice,
they do it automatically.
Most of those given that advice, won't respect it.
I've had to add two languages and its tough work,
learning vocab from an aboriginal language is
just incomprehensible to most people.
Bob had a hell of an advantage, his wife is a native
and she taught him a lot, Bob also had a flair for languages.
I remember how we both spoke some Spanish.
I don't remember exactly how fluent he was in Spanish
but knowing him, he could at least order a beer and find a way
to communicate.
He was also a "company man" and was part of management
but tried to insulate the junior pilots which was a tough job with
one of the greatest SOB of a general manager who used
to come on to the ramp in drunken rages and scream abuse at pilots.
That's another story
