Some people here already know, that I am from Germany, I came to this country 30 years ago, when I was 25.
Today ( bad fog day), I talked to my husband in german, he doesn't speak german, he kept saying " what"?, I would say the same thing several times and he just daid " what"?.
After I finally realized it, I asked him why he didn't tell me that I was speaking to him in german, his answer was, " you sounded so cute".
This has never happened to me, in 30 years.
So if you have brain fog and speak more than one language, it makes for very funny and interesting conversations.LOL
I may have been dealt a bad hand, but at least I'm still playing with a full deck. ( most of the time anyway).
