"Colleague couldn’t understand why parentcraft classes were “anti” natal." Oh god I'd forgotten tried to wipe it from my mind my ex thought this too.
He also had very odd ideas on how he thought the contraceptive pill worked, and how pregnancy dates were worked out (that latter one almost led to divorce! Meant a trip to the nurse to stop him thinking I'd been unfaithful! Nurse must have pissed herself afterwards so embarrassing) he wouldn't have it that
A Its dated initially from first day of last period when clearly I WASN'T pregnant, it's just a way of working out a rough date.
B that it's an estimate anyway! It's not to the exact day (he was away just 2 nights when I'd had that period) In my case I had a very light bleed that time and was later confirmed that actually I was already pregnant with dd at that point (implantation bleed maybe?) and my dates were adjusted - cue more confusion for ex and a conversation with his mum who had bleeds until she was 2/3 months pregnant with her 4. Dd is absolute spit of him so I can't help wondering if Mother Nature or whatever knew that he'd need it hammered home! When dd went overdue it was like a delivery he'd ordered was late! (she was only over by a few days!)
"All the geography ones have enlightened me." My geography isn't great I'm using sporcle etc to improve it, but a few things I knew. I wish maps were more accurate on size I find it so hard to visualise comparative sizes of countries/continents I'm not great on spatial awareness anyway. If I'm buying furniture I have to measure A LOT and even then I worry and I've had a few hiccups. My mum can just look at eg a sofa and know if it will fit, she's forever changing configurations of rooms too, drives my dad nuts! When he was still mobile he'd go into a room half asleep not knowing she'd done this and end up falling over the coffee table or stubbing toes!
I really struggle with (probably my age) "new" countries that have developed as a result of the countries I learned about at school changing or no longer existing due to various wars and political unrest. Mainly those that were formerly part of or parts of them were "old" countries like Czechoslovakia, Yugoslavia, ussr...
Trying to drum it into my head but I think it's harder to learn stuff when it involves "unlearning" something else? Anyone else find this?
Sympathise now with my parents and grandparents who struggled to remember such info when during the 60's/70's so many former colonies were (understandably and rightly) gaining independence from their colonising countries and, of course, changing their names. A relative is now retired from diplomatic service and they're often called on to check "so the country called X now used to be part of y and z countries is that right?" And even they need to google sometimes.
Just googled "accurate scale world maps" Africa really is absolutely massive! And Europe, let alone uk is tiny!!
"I didn't realise you could spend English money in Scotland until I was in my 30s" a lot of people are confused by this. Fellow scots will know the pain of trying to use scots notes in England! Tends not to be too bad close to the border but the further south you get the harder it is. Has also got a bit better in recent years but I've still had trips south where I've ended up having to go to an atm because a cashier refuses to accept its perfectly legal money.
"Little Miss Muffet eating the curtains away" I have the tv show "bewitched" to thank for teaching me curds & whey = cottage cheese!
"We’ve always called veggie shepherds pie “Sheep Turd” pie, because that’s what 1980s soya protein looked like." Veggie 30 years here OMG 😂 you're not wrong and Iirc we had to soak it for ages first too?
"Sheakspare: what is the difference between a comedy and a tragedy.
A comedy starts badly and ends well and the tragedy starts well and ends badly.
Explained by my DC, age 10." Brilliant!
"Been laughing at so many if these, mine relates to balloons. When my dad was 60 I was blowing up balloons to decorate and couldn't understand what I was doing wrong, they were all sitting on the floor with me not floating away like they do in pictures - my OH nearly choked laughing when I told him they were broken" I used to work in wedding industry, seriously embarrassed myself once when someone had to explain to me how balloon arches work (I had stupidly thought they had to somehow be individually arranged? 
)
"OH was an adult when he realised that it actually IS winter in Australia when it's summer in UK." As a child I thought that meant they did Christmas in June (I think someone may have told me this as a wind up and I believed them)
"That 'spendthrift' does not mean 'thrifty with spending'." Back to the weird contrariness of the English language. I'm seriously in awe of those who learn and grasp it so well when it's not their first language. Not least cos I can't think of one "rule" of the English language that applies universally. Other languages seem more...organised?
Scotch eggs - mind blown at start of high school when I learned it was possible to make them from scratch (pita though)
Re Tate & lyle/Tate galleries my granda told me this ages ago but he was originally from where one of them was from. To be fair Tate is a fairly common surname.
