We all have at least a few gaps in our knowledge—that’s no secret. That being said, it genuinely feels like there are some core bits of education and fundamental life skills that every grownup should be well-versed in.
Members of the AskReddit subreddit took to a couple of mind-boggling online threads to share the things they’ve personally witnessed other adults not know, from how elementary biology works to how (not) to treat others. Scroll down to read the seemingly common sense things they’ve had to explain to grownups. But be warned, you might want to cringe and facepalm.

That Freedom of Speech doesn't mean you can say whatever you want, without consequences of any kind. It just means the government can't arrest you for speaking out about the government.

That OCD doesn’t mean you like to keep things clean, it means Obsessive Compulsive Disorder. In simple terms it means you have a thing you have to do and if not done it’s like you cannot progress past that point wether it be beeping the microwave a certain amount of times, taking no more or no less than two steps per sidewalk tile or squinting your eyes when you blink. It’s a compulsion thing not a cleanliness thing.

You can get pregnant if you have s*x standing up. Had to explain this to a woman in her late thirties that had a teenage daughter.

Knowledge gaps are fairly common. And the irony is that you’re rarely aware of them until someone challenges your (lack of) knowledge. You can be strongly biased or woefully uneducated in a particular subject without even realizing it. For instance, because you misinterpreted something you (half) read in passing in a handful of headlines on social media one time without cross-checking claims and doing your due diligence regarding source reliability. Or you may have never had the time or opportunities to learn skills that seemingly everyone else your age knows how to do well.

However, if you have a growth-oriented mindset, you won’t see the mistakes you make as personal failures. Rather, they’re opportunities to improve and learn new things. By messing up you—hopefully—become more self-aware, open-minded, and willing to put in the work to research topics that are both new and the ones that you previously thought you were well-versed in. In short, you want to have the mindset of a real scientist, checking how your assumptions and hypotheses line up with objective reality. And that takes a lot of humility.

I worked in retail for too long.

One guys debit card declined, I told him so. He looked at me like I was an alien, and then loudly exclaimed, ‘how can a DEBIT CARD be declined?’ So had to explain that one to him.

Another person was traveling from a state that didn’t have sales tax, and expected me to remove the sales tax from their purchase because ??? apparently in their mind if you live somewhere without sales tax, you can travel the country and not have to adhere to those states rules I guess.

Another person tried to use a tax exempt card from another state (on Black Friday, mind you) and was mad that I couldn’t honor another states tax exempt card.

Honestly like it’s okay to not know stuff. But don’t be a f*****g a*****e when someone tries to explain to you what the hell is going on, lmao.

That $2 bills are real, legal US tender.

Got chewed out at a coffee job, for accepting "fake money", because a customer paid with 2, $2 bills. My boss was in their 40s. Took 10 minutes and a google search to prove I wasn't lying.

When I was 13 I had a 2 hour long conversation with a 19 year old guy about why r*ping someone is wrong. He just couldn't wrap his around why the victims can't just "relax and enjoy it". Never again.

Not me but my father had to do it. Parents were visiting my older brother, his friend was there, he finds out my father is an Engineer. Knows Air Conditioning well etc.

He tells my father, the central air in my house doesn't work. No matter how much I increase the power, it still doesn't cool. during winter I keep it at 70, but once summer came I increased it to 80 it still doesn't work.

My father looks at him... confused... then something clicks.

Slowly, my father replies, "The. Number. You. Are. Changing. Is. NOT. The. Power. It. Is. Temperature. If. You. Want. It. Cooler. You. Will. Have. To. Set. A. Lower. Number.

This was a guy in his late thirties and was an MBA.

One day at work, the electricity went out. One of the higher-ups made her way from her dark office to my dark office to ask me to look up something on the computer for her. I said I could look it up when the electricity came back on. She didn't understand why I couldn't do it right that second. "Because the computer runs on electricity."

Not only was that higher-up an adult, but she was highly educated with a Ph.D and everything.
