Curious PAX
My cousin was a skipper in the Merchant navy, firstly in UK then Europe, on Blue Water ie long haul container ships. His wife is Swedish, and they live in Germany. When their children arrived, a Dutch nanny was employed, and the kids grew up using Dutch/ German / English/ Swedish as a sort of alphabet soup. When they were small they would start a conversation in say English, and then if they did not know an English word they would borrow a German/ Swedish / Dutch one to fit. Made for some bazaar conversations. They are all grown up now but are still multilingual though the Dutch is a might rusty I think, but the language skills have definitely helped in their careers, and indeed outlook on life.
Cheers
