I never met my grandfather. Which means people can teach you, “give you advice” with their life.
Both my grandfathers died in the Holocaust.
My maternal grandfather was a lawyer. He was hardheaded. He violated every rule, he beat my grandmother, he was the “head” of the family.
When my mother, then 24 years old, found a way to avoid being taken to concentration camp, and told him, he said that she was stupid, and that she could just go herself. She did and she lived.
