The sparkler on the cake flickered, but the tension in the room burned hotter. Her husband stood by her side, yet the voices around urged her to surrender her feelings for the sake of peace. In that charged silence, she realized this was not just about a birthday—it was about reclaiming her right to be seen on her own terms.

I (29F) had a small bd dinner last weekend with my husband (31M), SIL “Lina” (27F), MIL and two friends at a normal but nice place. Lina’s an ‘influencer”. She films literally everything – plates, forks, ppl breathing.
Three days before, I wrote in the family chat – please don’t film me. Food, room is fine, just not my face. She said “got u”.
We sit down and within like 10 mins her phone is up. I say quiet, “pls don’t point it at me.” She goes, “you look great, it’s just vibes.” Husband backs me, “she said no.” Lina rolls her eyes, lowers it… for maybe 2 minutes.
Then the cake comes (little sparkler, staff singing). Lina stands and points the camera right in my face like, “birthday girl reveal!” I put my hand over the lens and said, “stop” I didn’t grab the phone or touch her, just covered the camera for a second.
She snaps that I “ruined her shot” and this is her job. MIL says to “let it go for one night.” I said that it’s my night – actually.
It got awkward fast. Server was right there, I felt embarassed. Husband tried to change the subject, but Lina kept muttering about how she had to scrap “everything.” I even paid for my own dessert (long story) and we left pretty quick.
Next morning Lina texts that I “humiliated” her and made her look unprofessional in front of everyone. MIL says I should’ve moved seats if I didn’t want to be in frame. Husband says my boundary is fair but maybe I “made a scene” by doing it during the song when eyes were already on me.
She’s posted me before without asking and co-workers mentioned it. I’ve asked her to blur/remove and it turns into drama, which is why I set the boundary in writing before dinner.
Conclusion
The original poster (OP) faced a direct conflict between their stated need for privacy on their birthday and the sister-in-law’s (SIL) professional need to film content. Despite setting a clear boundary beforehand, the OP felt compelled to physically intervene when that boundary was repeatedly violated, leading to embarrassment and friction within the family.
Was the OP justified in physically blocking the camera lens to enforce a clearly communicated boundary on their own birthday, or did the public nature of the setting and the timing during a special moment make their reaction an overreaction that escalated an already delicate situation?
Here’s how people reacted:
I can understand why others might want to keep it on the low due to it being in public but also that doesn’t make it fair that she was filming you explicitly after you told her over text AND at the dinner when you first walked in. And you also have nothing to do with her feeling or being “humiliated” when she did that to herself by ignoring literally every warning sign, you reacted and that’s normal. I would suggest to your husband to maybe keep a distance from her when you are at dinner, maybe asking to sit further away from her, not the best solution but something to maybe help?
Why are you being told you should have “let it go for one night” ? That is all you asked her to do….let it go for one night. Why is it ok for her to ignore a specific request for one evening, but you’re the bad guy for enforcing a pre-stated boundary for one night? Turn it back on the people who are blaming you. She is the one being unreasonable, not you.
Maybe in the future if it is your party, you can require everyone leaves their phone in their car, or have them put it in a box that you put away until after the event is over.
So here’s the thing, a restaurant is only KIND OF a public space, inside of businesses they may ask you not to film and/or require you to ask permission. Outside on the street, completely a public space, no permission required. HOWEVER, if you are asked/told by the subject not to film them your rights end where theirs begin, and they can make you take it down if they are the primary focus (in most countries and/or states).
Privacy matters.
