That is kind of glorious. And it does make sense when the person you’re emailing is gone for months. I did something similar my last mat leave except I didn’t explicitly state it, and lo and behold, people figured out that I wasn’t going to catch their email from a month or so earlier unless they brought it up again.
I would like to think that a professional translator would think to provide their out-of-office message in all languages that they translate. If anybody here is one, is that standard operating procedure?

I guess my first instinct might be thinking it’s rude but having seen it a few times I do get it. It really makes sense for people who get dozens or hundreds of emails a day and are gone for extended periods of time. It’s more courteous to be up front about it than silently delete like some people said they do (though I get they maybe just didn’t realize they’d need to do that).
I have a message saying I don’t listen to voice mail, because I only see that a message has been left after several days. No idea why the lag, it’s been the same despite going through two phones and two operators. There are always other ways to contact me. Last time I got voicemail it was the police, the officer was calling from a landline so he couldn’t text. Luckily it wasn’t urgent (he needed a witness statement, but I hadn’t witnessed anything of interest to the court).
