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.

    Hand wiping white furniture with a pink cleaning cloth and green spray bottle, illustrating basic cleaning knowledge for adults. 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.

    Adult using laptop on couch, illustrating moments when adults needed a reality check on very basic things. One day at work, the electricity went out.

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.

    Adult checking a young girl’s forehead for fever, illustrating moments when adults didn't know very basic things. I work for an early intervention program where therapists work with little ones in homes and daycares doing speech therapy, physical therapy, occupational therapy, etc. I had a parent get upset over the phone when I told her her child's provider cannot come to the home if the child has hand, foot, and mouth disease because it's contagious and since they visit several homes a day all day and also work with medically fragile kids, they can't spread illness around. She wasn't having it. We've had providers get URI's and gastro bugs and spread them around the office because parents don't let them know they or the kids are sick because they don't want to cancel appointments.
