When our oldest son, Jonah, was three years old, we had a seder with 20 Northwestern University students crammed into our 3-bedroom apartment. Jonah was used to lots of attention from the students, as I was the rabbi at Hillel at the time, and he decided he wanted to sit toward the middle of the table while Natalie and I sat at the head.
Just after we said kiddush, Jonah interrupted and said loudly, “Abba, I notice something.”
“That’s great, Jonah. What did you notice?”
“Well, usually on Shabbat, after we say kiddush, we have challah. But tonight, we’re having matzah.”
