It's difficult to take the author of the article being repudiated (Wingfield-Hayes) seriously when he has lived here for over 10 years and doesn't speak the language. Any other person who lived in a country for a decade and can't converse in the language would be (rightfully imo) shamed for it. Idk, say what you like about how journalists operate but living somewhere for a decade and not speaking the language doesn't…
I don't think you must've lived more than one place abroad, or somewhere with good English. For example I speak 4 languages, understand another 2, but don't speak the language of the country I've lived in for the last 3.5 years, and I'm not even learning. At some point it's just absolutely not worth it and I'm just gonna occupy memory that will be more useful for work or life.
This is the most common take you hear from people that never lived abroad, only speak one language, or lived abroad in a single place where they learn their first ever new language. Then judge someone who'd be learning their 4th or 5th. It's absolutely not the same thing for a native english speaker to learn one single foreign language when they move once and compare it under the same light.
