As did mine.
She told me that she was once slapped in the face by a teacher for not doing the Heil Hitler thing when passing him on the street.
At the end of the war the Americans were across the valley reconning the area to see if there were any German units in the area. According to mom my grandmother hung a huge white sheet from the 3rd story window of their house, which was perched on a hillside in the town, very visible to the Americans. A neighbor told her to take it down, because what if the Nazis saw it? My grandmother told her that she just didn’t care anymore.
The Americans moved across the valley and into their town and my family was rewarded for hanging the white sheet. My then 13 year old mother got the first candy bar she had eaten in many years.
Another family anecdote, my German grandfather was a construction foreman overseeing the construction of a stretch of the coastal defenses at Normandy. He was a great grandfather to me, died at 92.
Your grandmother was both brave and lucky. I read an account of a German woman who was with a group of refugees when she heard the news that Hitler had killed himself. She exclaimed, “Oh, thank God!” without thinking. An SS man shot her on the spot.
