I suspect you’re right. But at least she speaks four languages! Sigh...
Most of my German has dissipated over the years, but if one of those 4 was German, I’d sure love to test her. I was comfortable speaking in 2 dialects, Hoch Deutsch and Hunsruck. Back then, there were 14 dialects for an area the size of Oregon.
When my household goods were packed at the end of my tour, it was natural to speak their language. Later, a buddy of mine showed up, and he was wearing fatigues…he was fluent. One of the movers asked him, is he an American?
Ah, the good old days.
