In Italian, "non devi farlo" can mean both "you shouldn't / must not do it" or "you don't have to do it", which are almost opposite in meaning.
I already have accidentally insulted a colleague by forgetting the first meaning. Word for word it's devi = have to, non devi = don't have to, but oh boy.
The colleague in question is HR. She was not clear on my plan for the working day, so she asked "Allora ti metto un permesso di mezz'ora?" to which I replied "No no, non ho richiesto un permesso. Allora non devi chiederlo se non c'è una richiesta".
In my mind it was "you don't have to ask". My logic: save your time and effort, the request is the source of information, and if I forget to do one, you don't need to do the extra work of reminding me, that would be on me to handle since it's my responsibility.
You can of course imagine that if you read it as "You shouldn't ask"... She was rightfully indignant, and said that she may ask what and when she finds fit about leaves (permessi), whether there is a request or not, since it's her job. Yeah she's absolutely right.
I was horrified, and tried to explain best I could that it's a language fuckup on my side. My attemps were something like "non devi sentirti obbligata a chiedere" or "puoi chiedere ma non devi", if I recall correctly. It did not seem to convince her, so hoping my boss who speaks some English would understand, I said it's the "you don't have to" not "you must not". He went "Aah!" and gave a nod with one of those slow approving blinks. Nice, but then he didn't comment on that in Italian...
So I'm pretty sure I will just have to live with it, knowing my HR manager thought I was telling her to never ask me about my leaves...
I don't want this to happen again though. What phrase would work better?
I found "Non c'è bisogno chiedere", "Non è necessario", "Non serve", or "Non preoccuparti". None of these sound better to me, especially the last one (or maybe I'm being overly cautious now)
Thanks!
P.S. Putting this in writing I also realized that apart from that I was too short and robotic - "So you don't have to ask" is a bit too harsh and rude also in English if not made REALLY clear with intonation, gestures etc. So maybe I need to look for a more nuanced phrasing to begin with.
