Miss Katz is Sonia’s first introduction to critical thinking, and it’s telling that this is so fascinating to Sonia. Miss Katz, like Dr. Fisher, shows Sonia how a person can serve their community, especially by bringing up Father Gigante’s work for tenants’ rights. She highlights the areas where the local community needs help and points out the people who are stepping in to fix it, which gives Sonia a road map for later.
