My grandfather - my mom's father - was taken by the Nazis and used for slave labour in Germany. After the war, he had to find his way back home alone, on foot. His experiences fucked him up, and is one of the reasons my mother's upbringing was so difficult she effectively had to flee her parents at age 16, after having spent time in an abusive Catholic nunnery - unheard of in '60s Netherlands for a woman so young to strike out alone. It all destroyed the family.
