I once took my grandmother shopping on Avenue J, on a Sunday morning. There was no parking on J, and I ended up parking on Avenue I, across from Chaim Berlin. It was a nice spring day, and the windows of the yeshiva were open. We could hear the children learning from the open windows. My grandmother asked me if we could stop for a minute and listen. She told me, “I love listening to children in yeshivos learning! Hitler killed my family, and he tried to kill all the Jews, but here we are, listening to kids learning, and Hitler is gone! This is the greatest revenge against Hitler, having our children learning!”
