What obvious adult discoveries made you feel a bit of a plonker?

What’s something you learnt as an adult that made you think that’s completely obvious and yet I have never considered that….i feel like a bit of a plonker?

Mine was when taking tablets, the more you drink with it the better it will dissolve. I think alot of tablets are testing with the assumption people will drink 250ml alongside it.

That would be some unsafe pool.

BTW being working class does not mean people are not intelligent.

I think her point was "we were a very working class family with no real life experience of cruise ships".

I only found out recently that the swimming-pool smell isn't chlorine, it's chloramines that are released when the chlorine reacts with urine.

I’m autistic, so there’s a lot of stuff I’ve realised as an adult I took literally as a child. For example, if someone said in a book that the dog or horse “went to live on a farm”, I really did think without question it went to live on a farm.

Sorry I don’t quite understand this one - are you saying that was a euphemism?

That Arkansas isn't pronounced as it is written

you can say that about most words and names

@honeylulu I used to live in a country where hot water was provided from a central point rather than being heated in the house. So that's not so daft!

you don’t need to have experience with cruise ships to know that is a wild idea.

@backformoreofthesame that was the one that made me feel daft tho!

Same in Iceland!

Your fallopian tubes aren't connected to your ovaries and they just sort of use little finger like structures to waft / beacon the eggs in. What?!!

Slightly more embarrassing, birds don't sleep in nests. They just hatch eggs there and sleep on branches / in foliage or what have you.

That the swimming pool in cruise ships is not just a hole cut into the boat so you’re swimming in the sea. In fairness, we were a very working class family with no real life experience of cruise ships and I’d only ever seen them photographed from above. Add to this the fact I gave it no real thought beyond childhood, and I was genuinely surprised to discover the truth (for about 5 seconds until it became blatantly obvious) 🤦🏻

Some ships have a moon pool that is in fact a hole in the ship.

I mean he was good back in the day but not that good 😂

It's not just urine, its body oils, sweat etc. That's why you should shower before going on pools. And not pee in them too.

My father used to heat tins of rice pudding or soup or any food tins by putting said tins in a pan of water and then "boiling them until the label falls off" which indicated that they were done/cooked. This was presented to me as a bono fide known alternative to opening the tin and heating the contents in a pan. Keeps the flavour in and there's less washing up!

I never realised how odd this was until I was at university and asking my friend which method they were going to use to heat some rice pudding or soup or whatever. They looked at me like I was nuts and I remember picking up the tin to look at the instructions expecting to see both "methods" listed.

I was really surprised to learn this was something my Dad had devised rather than an accepted way to heat tinned food 😂

That the vagina is not smooth tissue. It is shaped like an accordion so it can expand when needed eg childbirth

“I just remember thinking me dry swallowing some ibuprofen might not be the most affective”

Sorry, but this really made me laugh 😆 You just used to choke down dry medication like an ostrich?! Didn’t it stick in a horrible lump in your throat? I’ve never in my life seen anyone do that!

I do that. if you poke it to the very back of your tongue it pops over nicely!

This one freaks me out! I had an ectopic and a tube removed and now I’m not even sure what’s happening anymore!

I thought the Falkland Islands were just past Scotland and I couldn’t understand why Argentina wanted them back.

My dad, an intelligent and well-read person, somehow got to adulthood thinking that it was 'chimley' not chimney.

Is that a northern thing? My fil says the same, he's from Lancashire.

Not me, but I was shocked some years ago to find that dh, who has a degree and prof. qualifications, and attended a very academic boys’ school, had never heard of photosynthesis. The whole process on which life on earth depends, was completely new to him.

I did not know that Austen Powers and Fat Bastard were both Mike Myers.

Abd he played a record company executive in both Bohemian Rhapsody and Michael, each for about 10 minutes and just sat behind a desk

That there is a direct relationship between the town of Paisley, in Scotland, with all its mills, and paisley pattern fabric. What makes it worse is that I live near Paisley, and it took several years after we moved here for this realisation to dawn on me.
