So why is this night different from all other nights? Because tonight, you get Passover food without Matza.*
Unlike the seder, that's unique. Only one night a year -- not even: only one night in those years that Passover starts on Saturday night.
Anyway, since we have guests this weekend, let me prepare for the Sabbath, and the holiday, by wishing all of my readers to whom it applies (or who wish it to apply to them), a happy Passover. (And, since I liked 'em, I'll recycle my posters from last year.)

* You can eat egg Matza, apparently, which is one way to do lechem mishna. So that sentence is an exaggeration.
