Also, you need to know your audience if you are going to go eccentric. Alison mentions that this message is fine in their culture, but it wouldn’t npbe appropriate for my somewhat formal field. And even if your workplace in general is casual, you might be contacted by someone outside. (In a tiny provincial courthouse I served in the past, there is a story going around that in the 80s a junior but elderly clerk used to address phone callers as hun and sweetheart and generally speak very informally. Most people thought it was funny, and then the President of Supreme Court called and… he didn’t).
Another (also memorialized via a TikTok) is not exactly an OOO responder but it’s a great example of unapologetic bluntness. “Baby, I’m not even here,” the woman in the says while preparing a margarita and talking about not responding to calls or emails during approved time off. “PTO? Prepare The Others. I’m a ghost.”

This information will help the person reaching out to you gauge whether their message can wait for your response or if they need to contact someone else instead.
I hate the overshare. It drives me nuts. I’ve seen a lot lately that say essentially “After this crazy year I’m spending some much needed quality family time with Jane and the kids doing abc.” yada yada yada. It seems like overkill and way too familiar. You’re spending time with your family-that’s not noteworthy. Just say I’m out this date though this date. Contact person if you have something urgent.
