Traditionally, at this point in the seder the "Four Sons" are talked about. 

The Torah refers to four sons: One wise, one wicked, one simple and one who does not know how to ask a question.

The Wise Son asks: "What are the testimonials, statutes and laws our God commanded us"

You should tell him about the laws of Pesach, that one may eat no dessert after eating the Pesach offering.

The Wicked Son asks: "What does this drudgery mean to you?"

To you and not to him. Since he excludes himself from the community, you should say to him: "It is for the sake of this that God did for me when I left Egypt. For me and not for him. If he was there he would not have been redeemed."

The Simple Son asks: "What's this?"

You should say to him "With a strong hand God took us out of Egypt, from the house of servitude."

For the Son that doesn't know how to ask:  you start for him, as the Torah says: "And you should tell your son on that day, saying 'It is for the sake of this that God did for us when we left Egypt.'"

Leader: One noteworthy thing the Four Sons brings up is this notion that all Jews throughout time were liberated from Egypt. We were all there and thus the Exodus in important for all of us.
