What Mumsnet universally accepted "fact" do you disagree with?

[BruceAndNosh]

MN Law decrees that all owners of personalised numberplate on their car must be twats
They also have more money than sense and are quite likely to also be rubbish at driving, and park in Blue Badge spaces on Thursday afternoons.
I love my Plate, I like the fact that I've had the same number on various cars for over 20 years.

And...
I touch raw chicken without afterwards soaking my hands in strong bleach for 10 minutes.
I also have a loo brush.

Are you a MN sheep, or a goat?

Gwen It's just another way to be bitchy towards another woman and cut her down to size. I'm not here for that.

Dress sizes are totally arbitrary anyway I go by weight

As soon as your child hits 18 they are an adult.

I know by law, they are, but only parents of 18 year-olds will know that this statement is ridiculous, particularly with the evidence that a young brain can take as long as 22-23 years-old to mature into adulthood.

It reminds me of the Kevin character, metamorphosing into a teenager as the clock strikes midnight.

• metamorphosising. Clearly a word I don't use much.

Chap - it's not about being bitchy. It's about not taking part in a communal denial of the obesity problem. We're getting bigger and we need to recognise that.

"Dress sizes are totally arbitrary anyway " - This is the point!

"I go by weight" - And then you get threads like 'AIBU to ignore my dr's advice re. BMI?' and I suppose you'd say any of us who disagree with that poster are 'being bitchy'.

That you should be grateful to be invited to a childfree wedding. Even if you don’t have any childcare and it would cost a small fortune to organise some. Because you are totally incapable of ever thinking of some childfree fun on your own and this will be the best fun you’ve ever had ever.

The pervading sense of entitlement from m/c mummies who have au pairs and the shouts of get rid which erupt if the generally young and possibly homesick au pair does not meet expectations. Frankly, it sickens me

That all Tory voters read the Daily Mail and should hang their heads in shame.

My kids are sometimes horrible or difficult. This isn't my fault & they don't have SN or mental health problems, either.

I don't need to clean things frequently; I don't care how often other people clean themselves or their things.

Being 'well-groomed' doesn't make me feel more confident or even simply better about myself. You being well-groomed won't make me think you're a nice person or better at your job, either.

I don't agree that most health oddities are 'worth getting checked out'.

Something of a consensus on this thread of everyone wanting to be seen as maverick and different, when none of the opinions are that unusual!

Yes! It's just another random and gratuitous opinion basher in disguise, where people make random and untrue generalisations.

Gwen - I would never tell someone to ignore medical advice it's dangerous but going on about dress sizes is a way to bash and bring down another person by telling them they're not the size they think they are! It's horrible and, yes, bitchy. You wouldn't say it to a man - oh well you think you're a 30 waist but you're really a 34 due to vanity sizing. It's nasty behaviour.

Yes we have a problem, people are getting larger but at the end of the day if someone is overweight they know it themselves they don't need someone wittering on about how they're not the dress size they think they are !

But the MN miracle chicken is a real thing. I still can't work out why. . A £3 chicken does actually feed 4 people for 3 meals. So that's 12 portions. I think the meat is so pumped with steroids, it grows back in the fridge overnight. Joke or not, it really does.

That asking for money as a wedding gift is rude. I bloody rejoice when people ask for money - saves me going to the shops. And literally what's the difference? Unless you're exchanging your gift for sex or maybe nectar points, won't you be spending money anyway?! The way some people wang on here it's like the bride and groom have asked for a kidney

What’s wrong with having a toilet brush ?

It's still very London and SE England centric. Assumptions that everyone suffers in the summer 'heat', that it's normal to have a long commute, etc

Yes - this really shows when posters refuse to believe there are places with no public transport

The idea that trans people represent a terrifying threat to women-only spaces.

That dead beat fathers must have contact come what may.

That "Free Child Care" means you have no say whatsoever on how it is carried out.

Tell me how personalised number plates aren't a waste of money?

I'm interested.

I don't give a shit if anyone has one or not. I get some people like them. And I also think people can spend their money in whatever way they wish, whether or not they are spending frivolously, if they have it to spend.

But I'm interested to hear what about them gives value.

That all teachers have gone into the job to pick on MNers' children specifically, and without exception.

That MNers in general know better than anyone who has studied for years to do the job they do. The fact that you can google doesn't make you a doctor love.

That all next door neighbours of MNers are vile examples of the human race whilst all MNers are model neighbours, have model children and are deserved of immediate sainthood.

That people seem to have time to watch box sets/full TV series 24/7. Who are these people? How do they get fed?

That using the words "feeling a bit hormonal" lets you get away with any manner of despicable twattery. No, it makes you look like a twat who is prepared to use your sex to do vile things and not get called out on them. It's the mammy forum equivalent of the 1950s fluttery eyelash heavy breathing shite, and arguably no more advanced.

That MILs by nature are hideous creatures out to ruin your life. Which is odd, given that your own mothers, if you are married, are by definition also MILs, yet the very pillars of rectitude.

That you are somehow bigger, better, cleverer because you think you're the first person ever to have noticed the "Chester draws" spelling. My, how our sides split every 20 minutes when we read that one.

Not so much the miracle chicken- but the fact that on the "what's for tea" threads, everyone who posts is having a Heston Blumenthal 16 course extravaganza with 5 types of veg, a starter and a (healthy) pudding.

(obviously we know that it's Monday night, it's November, and they're all having beans on toast or a takeaway like the rest of us, but let them believe their own fantasy life)

You could class anything you don't need as a waste of money. My DH won't pay for fairground rides for dd as he says it's a waste of money. However, she enjoys them so I don't class it as a waste because to me the pleasure she gets is worth that money. Similarly, if having your own number plate gives you pleasure then it's not a waste of your money (to you).

That if you have a dog who doesn't behave perfectly all of the time, then it's always ALWAYS your fault and this is usually based on very little information. "My dog barks too much" - "it's probably because you're a crap dog owner and generally, just a terrible person".

That a random book from the Works or a heavily discounted toy from Argos is a good birthday party present.

I'd always much rather have a small toy/book that is actually worth £7, than something which is discounted from £15 and actually worth about £3 and was chosen because it looks like it cost more than it did.

Don't buy me a cheap hardback of a crap book from the Works. Go to Waterstones and spend £7 on buying me a copy of the book you and your kids have read every night for a month. Yes, it will look a bit small and cheaper next to some of the other presents. I don't care. We'll probably still be reading it this time next year.

A small decent present is much better to receive than a big cheap one.

One that always makes me laugh - the amazement expressed when someone says they are not on mains gas, because it doesn't exist in their area. "What, you haven't got gas?" (faints away). Also that people can live in areas where there are no shops within 10 miles, no public transport, and certainly no takeaway deliveries. Surely no one can actually live like this?
People being described as elderly, and then discovering they are in their 60's. As a 63 year old, I don't feel any different to how I did in my 30s. I find there is a certain amount of ageism on here, and if you are a baby boomer you deserve to fry in hell.

I don't agree:

that private education is better than state (it isn't)

that Ottilie is a nice name (it's horrid and sounds like a spoilt heiress in an Agatha Christie drama)

that "No is a complete sentence" (technically, yes, but it's a really fucking rude sentence)

that Waitrose sells better quality food than other supermarkets

that Jo Malone candles are worth the money. Pffft.

I do love MN though
