Your favourite unreasonable AIBU?

There are so many wonderful examples of these, please share your favourites. Bonus points for links.

I remember one when OP was annoyed if the cost of children's birthday gifts weren't higher than the cost of hosting the party per child.

And the classic from a few weeks ago when OP thought it was ok to block the shared driveway and thought their neighbour who lived at the end was the unreasonable one.

I bet there are better ones out there though...

Not really an unreasonable AIBU, but there was one a few years ago about a dog running onto someone’s picnic blanket and causing mayhem. There may have been wee or poo involved or I might be making that up, but there was definitely scoffing of food. There are similar threads on Mumsnet from time to time (there was one a week or two ago) but the OP’s description of what happened had the tears rolling down my face. I wish I knew where to start looking for it.

There was 1 a few weeks ago no wee or poo involved. The woman and child ran away and the dog eat all their food. Took a while for owner to come looking for the dog.

Just today, there was a post for a recipe for 1 (ONE) person that involved a whole BNS, 500ml of cream, something like 1.5 tbs of chilli powder, etc.

OP insisted that it was real & not a troll post.

Sounds very much like this "recipe for one"

500g pasta.... that's just to start 😆 I think there's 3.5 tbs chili powder in this one.

Sorry, not aibu- but ridiculous nonetheless

Butchyrestingface · 31/07/2025 00:02

I can never get over the husband and the OP's university assignment one, and what he did to it in a fit of orgasmic rage.

Sadly, that one seems to have been removed.

Rival child benefit thread

Spare room in holiday cottage so that it was free if someone needed a break or was ill. And for some bizzare reason OP was convinced her child would have to share with her uncle

It's got to be the supersoaker one. Sorry can't find it right now but think it's in classics, will try and search later.

I also found one fuming about people who pressed the button on traffic lights, but then crossed when there was a gap in the cars so that by the time the lights changed to red cars had to stop at an empty crossing funny. Yes it might be mildly annoying but the OP couldn't explain how it actually affected them once the button had been pressed they were stopping either way, it wouldn't make any difference to them if someone was actually crossing in front of them or already half way up the road.

Those stuck in my mind because they're funny and because the OP was so clearly unreasonable 99% of people disagreed with them, the other ones I remember are the ones that blew my mind how many people think so differently to me (as in I read the heading thinking "what a silly question, of course it's going to be 100% YABU to then be completely gobsmacked at the responses) are boys over 8 using a female changing room and one years ago about if there was a fire would you save a child or your dog/cat.

Edited

Oh my ex used to insist on waiting so we didn't piss driver's off. He was actually quite an intelligent bloke both of us non drivers btw. But trying to explain to him the red and green men work in with the traffic lights they just let pedestrians know when it's safe to cross as the traffic lights aren't always in view. Just went in 1 ear and out the other.😂😂😂

The one where OP invited a romantic interest on holiday, realised she didn’t like him that way and then went AWOL, then booked him a flight home the same evening and he had no idea what he had done wrong 😂

Oh please someone find me the link to this! Sounds mental

And another one-something to do with getting pizza delivered to the school for her daughter,school had refused but she insisted it was the right thing to do? I can't remember what it was called though, sorry!

i just nearly choked on my toothbrush reading the WILLY WILLY WILLY one

One I remember is from many years ago and I can't find it. Also, I think it was on the property/DIY threads instead of AIBU. However, it stuck in my memory because the poster was so certain she was right.

She was a law student who had recently bought a house, and there was a small enclosed passage between the houses that was jointly owned by her and the next-door neighbour. So quite unusual circumstances really. She said that because the neighbour didn't use the passage, she planned to claim it and make it into an additional room in her own house. The justification for this was that she and her partner needed the extra space more than the neighbour did.

Everyone kept telling her that she couldn't just claim a shared space as her own and renovate it. She kept saying that as a law student, she was sure this was legally possible.

As the thread continued it emerged that the house was listed (so the possibility of making changes to it would be legally tricky anyway) and that the neighbour herself was a solicitor or barrister (I can't remember the details).

The OP wrote a letter to the neighbour informing her of her plans, and the neighbour said no. The OP persisted, and the neighbour told her in legal language and in no uncertain terms to piss off.

Everyone on the thread was on the side of the neighbour, but the OP was aghast at the neighbour for being so unsympathetic to her plight of needing more space. She was sure that her plan was eminently reasonable and that she would prevail.

Threesome went wrong!
He wanted a threesome and she ended up having all the fun with the other woman and ended her relationship in the end I think!

Nothing beats penis beaker or screaming at art but I did enjoy the one with CF Barbara stealing the allotment from her new neighbours. Think another neighbour was trying to steal a garage too. OP was completely reasonable but the audacity of everyone in the houses around her was just amazing.

I actually didn't like the sound of the op and felt a bit sorry for Barbara.

The one currently going on about till receipts. The OP is getting a bit het up!

Agree about this one!!

My absolute favourite that sticks in my mind, is the woman about this time last year, who was getting upset because her son was organising a Halloween party for his friends and siblings. So all the guests were similar age to her son and his wife. And the poster was really upset that she hadn’t been invited and was asking “AIBU if I just turn up anyway?” Every single poster said along the lines of no, don’t, you’re not invited, let your son and his wife just have their party and enjoy it.
But she just WASNT having it and kept telling us why she felt it was best if she just went along. didn’t take on board a word of advice anyone asked. Also it was generally funny that a Halloween party was being organised SO far in advance.

The Mexican house thief

op had a holiday home im Mexico and it turned out that friend she had hosted in the past just went there for a holiday when the op
was back in the uk

OP didn’t know they were at her holiday home

Mexican house thief didn’t ask to stay
and I can’t remember how they got caught out

But I think they had done it a few times

It was very rough on Anne, going through puberty, to have to share with a middle-aged man (and probably embarrassing for Fritz too). Since Mr and Mrs Frank already had their privacy compromised by sharing with Margot, I agree that arrangement would have made sense

I think so too.

The one where a woman on Youtube posted photos of herself and a much younger and more attractive Youtuber who looked nothing like her and said they were nearly identical, then claimed not to be the older woman.
