A random day

Let us begin by summarising the movie. There lived a Polish-Jewish pianist in the midst of World War II. As Germany took over Poland, Jews were hunted down, and he was no exception. The movie unfolded with various scenes in which Jews were tortured, shot, flamed, and even bombed. The pianist met several people who helped him in hiding away from the Germans and fed him. He survived the Holocaust. But his survival provoked a rippling thought inside my head.
