AIBU to take a vow of silence and never talk again? Why am I such an idiot?!

[BeauMirchoff]

I had an induction day at my new job a few days ago. We had a buffet in the afternoon and some of my most senior colleagues attended. I do know most of them because I worked for them on temporary basis last summer.
As I was talking to two of them (very senior, both 20+ years in the job but very approachable and always up for a good laugh), another colleague approached. And as she did, she said something in French and the other colleague said "oh, I have no idea what you said there" and I, with my big mouth, went "oh, she's swearing at you in French!" It was supposed to be a joke and they did laugh but the colleague who said it didn't look pleased. She said "blimey, you need to sort this one out!" and pointed at me.
I was, and still am, MORTIFIED! Why am I such an idiot?! My big effin mouth i swear, next time I'm juta going to stand there and nod.
Please tell me I'm not the only one whose mouth always gets her into trouble?

It was a joke and taken as such by senior colleagues.

Why was other colleague speaking on French when nobody else did?

My guess is she was trying to exclude you by speaking French and then was mortified that you got the laugh from senior colleagues.

Her job is to do with languages! I think she thought she was being funny... Seriously can't shake off the feeling of total embarrassment!

Yep she did, and was trying to do an "in joke" type of thing to make you aware of your place in the dynamic.

It back fired on her and she was fuming

You unwittingly knocked her back down a peg

I think it was rather inappropriate on an induction day really. When you get to know people, and their dynamic, you can make jokes like that. But when you don't know them, particularly if they're senior and you're new it does come across badly.

OP worked with them last summer so there is an established relationship.

You sound epic.

Come and work with me?

I don't think it's bad at all - it's funny! She just didn't like it.

If she knew nobody else speaks French then she was rude before you were!

Just forget about it OP....but watch your back

I'm sorry that's hilarious. Sounds like you put her back in her place!

Witchend - I'm not asking whether what I said was inappropriate or not. Not asking for your judgement. I know perfectly well it was inappropriate since I already said that I feel embarrassed.

Really not so bad! Don't beat yourself up!

Don't be embarrassed. Your colleague was a twat in assuming you couldn't understand her. She got caught out. Her bad.

I wouldn't worry one bit about it, OP. Enjoy the new job.

I don't think the speaker was swearing actually, the OP just said she was as a joke.

You'll probably get away with it as a one-off, but if you do have a tendency to 'chip in' with jokes like that you already know that it doesn't always end well!

I think it's really funny. If I had been the other woman I would have said "shhh" to you in a conspiratorial sort of way and laughed it off.

The fact she had the hump speaks volumes and makes me think PP are correct that she was threatened by you and trying to put you in your place. I would avoid her for a bit

Do be embarrassed you caught her out, she shouldn't have been so rude.

Should say 'DONT be embarrassed'!

OP, can you just clarify something please? The colleague who spoke French wasn't swearing really was she? You just said she was as a joke, right? Because I think some of the previous posters think she was swearing and was annoyed you told the others.

Oh don't worry, the senior collegues did not understand it, she was the rude one. For all they know, she could have been swearing at them in French. Yes I think it did backfire on her!

I don't think she was swearing! All we heard was "douche"
I might avoid her for a bit and maybe just limit myself to 10 words per day

Thanks, bluebeck I would have done the same!

She was doing it to exclude you. I saw something similar once. It's a twat's trick.
