Well, yes... all this reminds me my old boss who spoke fluently all the European languages and he enjoyed communicating to all the tourists they'll come to his restaurant...
Also reminds me the old joke,
-How do you call a person who speaks many languages? -Polyglot.
-How do you call a person who speaks 3 languages? -Trilingual.
-How do you call a person who speaks 2 languages? -Bilingual.
-How do you call a person who speaks 1 language? -American.
(No offense intended to all the fine Americans in this forum who are actually very proficient in Spanish and many other languages... but somehow, the attitude of the boss at the beginning of the thread reflects a bit of that...)
I'd tend to admire someone who speaks 10 languages more than one who speaks only one, unless that only language is mastered with such skill that is impressive... (But I tend to see that even the great writers don't get fixated in one single language... Reminds me "En Attendant Godot" by Samuel Beckett, Irish guy writing in English and French, or the Spanish Moratín, translating Shakespeare... and writing his own work...)
At any rate... it reminds me too this old poem/song (I don't remember the author) (Well, yes, I found it googling it, of course...)
Admiróse un portugués
al ver que en su tierna infancia
todos los niños de Francia
supieran hablar francés.
"Arte diabólico es
-dijo torciendo el mostacho-,
que para hablar el gabacho
un hidalgo en Portugal
llega a viejo, lo habla mal
y acá lo parla un muchacho".
(Nicolás Fernández de Moratín)
(Sorry if I am a bit rambling... but these are my 2 cents, or 4 or 5 Euros...)
Let's say,
"Mi granito de arena..."
