We say it all the time, many times without really thinking about it. We wish each other a good shabbos.
When I started doing chatzos years ago, it was a novel idea, and people in my community would joke with me – they would see me on a Tuesday and say, “Hey, it’s Tuesday, should I wish you a good shabbos now?”
Sure, why not?
Good Shabbos to all my chatzos friends around the world. May you all be blessed with shalom in your homes.
