Describe Ruth’s mother’s experience in Poland.

"My father would say, “I’m a citizen and you’re not. I can send you back to Europe anytime I want.” He used to threaten us with that, to send us back to Europe, especially my mother, because she was the last of her family to get here and she had spent a good deal of her life running from Russian soldiers in Poland. She used to talk about the Czar or the Kaiser and how the Russian soldiers would come into the village and line up the Jews and shoot them in cold blood. “I had to run for my life,” she used to say. “I held you and your brother in my arms as I ran.” She was terrified of Europe and happy to be in America."
