This week is Passover. The holiday in which we commemorate perhaps the most important family story ever told: the Exodus, the moment that transformed the Jewish people from a tribe into a nation. The Seder doesn't leave the what, the why, or the how up to chance. And embedded in its liturgy is one of the most remarkable parenting insights I've ever encountered: the four children — the wise, the wicked, the simple, and the one who doesn't know how to ask. Four children. Four different ways of receiving the story. Four different responsibilities for the parent telling it.
