Just back from visiting a friend abroad. We met 20 years ago as young expats in the European country she still lives in. When I lived there, she didn’t speak the language at all. In fairness she was employed as a nanny for a family who only wanted her to speak English with their children. However they also offered to pay for her to take private 1-1 classes with a tutor to learn the local language. She declined as she didn’t want to ‘study’ in her spare time. I worked for a company where English was barely spoken so I was forced to learn the language and I accept that if I was in her position I may not have become as fluent as I eventually did.
However fast forward to now. She no longer works and is married with children. She still doesn’t speak the local language beyond the bare basics. I stayed at with her family and her husband (a local) and children spoke to me in their native tongue. My friend only spoke English which is fine between the two of us but she cannot speak to her MIL who was also there but doesn’t speak English. I’m a bit baffled. The local language is hard but…20 years?!!
