When I was in the seventh grade and my brother was in the third, we had to live with my aunt for a year due to family circumstances.
My aunt lived in a small military town. It was not formally closed, but was located quite deep in the forest, so that there were almost no strangers there, every new resident was an event, and theatre, cinema, circus, which were not there, the locals replaced with gossip. They tweeted about everything, starting with the children in the upper group of kindergarten and ending with honorary colonels.
In general, three days after our arrival, everyone in the city already knew that we were in fact no nephews, but extra-marital children, whom Sophia Aleksevna’s husband walked on the side, and she (a holy woman!) Accepted in family!
By the end of the year, the whole city was solemnly convinced that Sophia Alekseevna was a holy woman, but a bad wife, because the husband of a good wife would not walk, and her husband - well, not without weaknesses, of course, but a good man, the children were not abandoned.
I still don't know why nobody came to mind that my brother and I are both a copy of my aunt (she's my mother's sister, they can be confused to this day) and Nordic blondes, and my aunt's husband is an ethnic Armenian with a corresponding appearance...
