Hmm my grandfather (father's side) was transported to a Nazi work camp in the second world war where he spend many years. He never wanted to talk about it. Yet since he is no Jew, Roma or Sinti he would have been left out. (He died 5 years ago)
My grandmother (mother's side) spend time in a Japanese concentration camp where she lost her first child from malnutrition. Why pry open old wounds with this almost 75 years later.
