It's still very useful to be fluent in European languages but I agree, 'Asian' languages (eg Mandarin) are wonderful and on the up and up. I looked up a nearby comprehensive and they offer 'Chinese' as an 'enhancement'. Other schools have been doing Mandarin for nearly a decade. Wish I had had the opportunity but glad others do now.
I'm impressed by people who have learned conversational dialects, would love to (including Yiddish!). So useful at work and when travelling (I don't do extensive travel but plenty of others do). Still i'm not especially skilled at languages beyond O level, except for being good at my own (prob'ly doesn't show here :-), where I'm careless), doesn't bother me but iwould certainly encourage younger ones.(My younger one & niece who went to same school were offered Mandarin - not to exam level- and niece took to it like a duck to water!)
