Passover used to be my favourite festival. The huge build up to it, especially swapping all the dishes over (I imagine it is like what it must feel to a child in a family that celebrates Christmas, when you bring the boxes of decorations down from the loft and start putting them up), the organised chaos of the Seder, the special roles of children during the Seder, the delight from the adults when we demonstrated our learning.
The Seder is a ritual meal with the express purpose of making you ask questions, discuss and debate the story of the Exodus from Egypt. Songs, prayers, stories, rituals, foods to taste. Then a slap-up meal, followed by more songs, prayers, stories, rituals and games.
Our Seders would last for hours. We could easily sit down at 6pm and not finish till after midnight. We usually had Mum's best friend and her family, plus dm would always find 2 or 3 more people who didn't have a Seder to go to, foreign students, for example. Children regularly fell asleep at the table - nobody was sent to bed before it finished. That would be the first night. For the second night each family would go to a different friend's house for the second Seder. Which would be subtly different, with different traditions, different recipes for the same foods, and yet identical to our Seder.
And the food! Passover food is amazing! A whole separate thread would be needed to explain it. But it is lush.
Swapping all the dishes back after the week was never as much fun.
