Traditionally, The Four Sons (or Children) include a wise son, a wicked (or rebellious) son, a simple son and one who does not even know enough to ask. Each of the first three ask questions about the Seder, essentially "Explain all this to me - what are my responsibilities?" "What has all this nonsense you are babbling about got to do with me?" and "What IS all this anyway?" while the fourth is silent - requiring the adults to be proactive in providing an explanation of the Seder proceedings.
