To ask for examples of the worst behaviour you've seen from an adult at a wedding?

Attended one yesterday as a bridesmaid. The brides cousin was also a bridesmaid, spent the whole morning clearly aggrieved that the day wasn't about her... smoked in the getting ready suite and had to be told to put it out, then lit up again and claimed she had forgotten when the bride told her and made a snarky comment..then presented her silver converse she had customised to wear with her dress as she "doesn't really do heels"... the bride ignored her and sweetly said "at this point I don't think I can stop you" as she knows what she's like then what do you know, she wears the heels! There were loads of instances like this all day and she is 28 but seemed to want to just be am inconvenience all day which I assume was jealousy...even little things like being late for photos and pretending not to hear when called over, pushing the food round her plate, really ungracious behaviour. The wedding was fantastic! She could have really enjoyed it much more. Not really an aibu but whats the worst behaviour youve seen like this?

The best man was the groom’s flatmate. He culminated his speech with a story of the groom coming home drunk one night and being discovered by the other flatmates squatting on the kitchen floor with his pants down, trying to push ice lollies up his bum. Apparently he suffered from piles.

Thanks, best man. I really wanted that image in my mind while dessert was being served.

At least... he SAID he had piles...

My dh's cousin got married and her dad just went home after the meal - no incident of any sort had happened. He just decided to go home. It was a big, formal wedding and everyone was shocked. His cousin was so upset- her dad didn't even tell anyone, just walked out.

Oh, he'd have had his reasons. It's just that the wider family have not been informed about it. Maybe the dad didn't even tell his daughter in case the reason was even more upsetting. Maybe he couldn't stand his new son-in-law, but kept his thoughts to himself and his daughter had no idea.

Maybe he has a secret health condition that he hasn't even told his daughter about, never mind the wider family. Or a secret alcohol problem.

Maybe he has severe anxiety and just had to run, and the daughter isn't aware of the extent of it because her dad doesn't want her to know, but he put himself through the main father of the bride duties for her sake.

Maybe his other half had just told him she wanted to split up or regretted marrying him (or whatever other awful revelations could prompt someone to just leave suddenly).

In families, you just never know what's going on in someone's life unless you're living in their home and witnessing the day to day goings on for yourself.

I was at a wedding, where the groom fell massively in love with a colleague, who was also a guest.
I saw this, it was really like a lightning strike.
The couple marrying had been together for 8 years.
It was incredibly sad.

I was wondering if the groom had said the name of the person he was actually in love with during the vows, like the episode of Friends. But have just realised that he possibly didn't even know it 😯.

EconomyClassRockstar · 11/02/2026 00:37

Back in the dark ages when I sang in the church choir as a kid. Best man puked on some flowers and the maid of honor fainted half way through the service. The bride and groom looked decidedly peeky even to my not very well trained 10 year old eyes.

Was the church Catholic or Eastern Orthodox? Not the same thing.

Eastern Orthodox. But as I always understood it that is more like Catholic than Church of England.

A very well known (BBC type) guest spat at the venue manager who asked him to extinguish his cigar. (Very notable/landmark type of venue). Then followed with a sea of expletives, telling said venue manager they would have no job in the morning, as the world’s best security escorted him downstairs and left him on the floor, external to the site.
Venue manager was a much younger me. I remained there for a further two and a half years & received the biggest box of chocolates I had ever seen from Fortnum’s with a huge bunch of flowers from the happy couple on the Monday morning. Turned out they barely knew this guest but had caved under pressure from the father of the Groom.
Still chuckle to myself when I see this guest on tv behaving as if butter wouldn’t melt 😂

Do tell?

You drank too much the night before, you nearly knocked over the bride, you left the church then came back in whilst the service was taking place, you cried through the reception then left it to go to your room, you left your children in other people's care, your ex had to miss his brother's speech to try and stop you being so dramatic, you think your mil's day wasn't affected by your behaviour and you think everyone else apart from you had a lovely day ...oh yeah, you're an absolute peach!

Yes, but as someone whose mil did this, the difference is telling people .

It's not fair to leave without a word to anyone, spark a manhunt and leave people panicking. A simple "I'm not coping" it's time to leave would suffice. People might be disappointed, but they'd ultimately accept it.

I wonder why it was then at the wedding that it happened when they obviously knew each other as colleagues already - or was she a colleague of the bride?

maybe the romance of the day and everyone dressed up?

Yes, I couldn’t work out from original comment whether she was a colleague of the bride or the groom; i.e. did they meet for the first time at the wedding? It’s the stuff of romance fiction.

I decided not to have bridesmaids or flower girls at my wedding. One of my cousins was very offended by this. On the day she turned up with her daughter dressed in a flower girl dress. She even had a little bouquet. Her son was in a 3 piece suit, complete with tails😳. Moving on to thr reception, her brother, who has rsvp'd to say he couldn't make it, turned up with his wife and their 3 dc. No place settings because he'd said they weren't coming. To top it off, he'd come straight from his shift as a bus driver, and was still in his uniform...

Edited

What happened about the no place settings ,?
I always wonder what happens when people turn up and there's no meals for them

SmudgeButt · 10/02/2026 14:27

Not a problem at the reception and not randy like the other comments but....

My friends from high school were finally getting married. It was great on the lead up to the wedding which was delayed for 2 years because her grandmother and aunts needed to hand embroider the dress as her family was Ukrainian and very traditional. Despite this and getting married in the Eastern Orthodox Church (so very Catholic) it had been agreed that the service would be all in English as the groom wasn't Ukrainian or even Catholic. The priest would do one blessing in Ukrainian and then the standard English ceremony lasting about 15 minutes.

Come the day of the wedding the priest was called away to give last rites to some old boy and a different priest agreed to do the ceremony. Two hours worth of wailing and chanting in Ukrainian and Latin complete with waving incense about. We told our groom friend that we would vouch for him if he wanted an annulment on the basis that he didn't know what was happening throughout the ceremony as apparently the first part was baptising him as a Catholic.

Eastern Orthodox is completely different to Catholic. In fact it exists because the broke away from the Catholic Church in the 3rd century. It wouldn’t have had Latin I wouldn’t have thought.

Im not being an arse, I’m ND and studied theology so find it hard to not respond!

Not good not being able to understand any of your own ceremony though!

I was at a funeral where I watched in real time the local sleazebag hit on the grieving (very wealthy) widow. He was so blatant that I nudged DH and said 'look at [name] move in on her].

They married 3 months later.

It's her 4th marriage and she outlived all the other 3. So a watching brief, perhaps.
