How different is this night from all other nights: This was included in the Haggadah for those who did not have a child to ask questions, as it says in Talmud Pesahim (116a), "If his son was knowledgeable, he should ask; if not let his wife ask him. If she is unable let him ask himself. Even two who are knowledgeable in the laws of Passover should ask one another."

We do not dip even once: The eating of vegetables at the beginning of the Seder is called dipping since it is the practice to dip the vegetables in vinegar or in haroset.

This night we do so twice: There is the first and the second dipping. The first dipping is not obligatory but is meant to make children ask, "Why do we eat vegetables before the meal and on other nights we do so during the meal.

On this night everyone leans: Even the servant must lean; so too, a son may lean before his father and a woman of important status, since this is a sign of freedom and authority.
