One idea is that the Ma Nis aren’t just about being curious. They help involve every generation in the story of how we became free. The child asks, and the parent answers, but these questions show how amazing freedom is. For years, we’ve been trying to answer these questions — "Why is this night different?" — to really understand what freedom means. It’s not just about remembering the past; it’s about making sure every generation knows how important freedom is and how much faith helped us get there.
