As clever as we might think we are, we all have gaps in our knowledge. After all, it’s impossible to know everything about our world. You might live your whole life believing that dolphins are land mammals who swim just for fun. Or assuming that a “birthday suit” is a specific set of clothes people wear when they turn another year older. Then, when someone points out that it’s completely not true, you can’t help but wonder whether others thought the same as you.
Well, negan2018’s post on Ask Reddit revealed that there are plenty of people who have also experienced these embarrassing moments. The user asked fellow community members, “What really obvious thing have you only just realized?” and thousands started sharing their stories.
As they say, the more you read, the more you know. So get ready to take a deep dive into some of the best answers we have collected from this thread. Make sure to upvote the ones you enjoyed most and share your own little misunderstandings in the comments below!

I recently realized I was allergic to carrots. I just thought they made everyone’s mouth numb, you know, just like almonds…. I also learned recently that I have an almond allergy.

The first time I visited the USA I was on my own and in NY and going to all the museums. I kept seeing signs that said “No strollers” and thought, because we call strollers prams in the UK, that you guys are super strict about the proper amount of attention required to visit a museum. I actually pretended to show more interest than I had in order not to be thougth of as some deadbeat out for a casual stroll.
It wasn’t until about day three that I saw a “No strollers” sign that included a graphic for idiots.

I must’ve been around 11-12 years old, when I realized that “in order of appearance” during the end credits of a movie doesn’t list the actors/actresses by who is the most good looking.

This girl I know has a dog named Deoji. Two years into knowing her and being around Deoji, I was having a conversation with her sister in law and I said “I love the name Deoji, how did she come up with that?” Her sister in law responds, “Deoji” and I said “yea, it’s a neat name”. She started laughing and said “No, D.O.G. …the way you spell dog”
I’m still mindblown about this lol.

I only just today realized that the “walk the plank” plank on a boat is not a special addition pirates added to their ships as a means of public execution that looked like a little wooden diving board.
It is, in fact, the very same plank as the gangplank you’d normally use to get on and off of the ship. It is not the presence of the plank that is threatening, but the absence of dock.

Not me but my sister asked me about 2 and a half months ago when we were watching John Wick 3 during the desert scene she asked me if they were real and I asked if what were real and she said “Sand Lands” and I busted out laughing so god damn hard and said “you mean deserts? Yes they’re real”. Thinking about it right now Got me laughing.

I realized that to be in one’s birthday suit it means to be without clothes. I thought for the longest time it was a specific set of clothes you would wear on your birthday each year. I found out when I asked, “what happens when you don’t fit in your birthday suit anymore?” Lol

My grandpa used to ask me when I was a kid if I could talk without moving my lips. Being a dumb ass kid I would always give it my best effort, and thought I was pretty good at it. 20 years later I realised the old bugger was just telling me to shut the f*ck up haha. Too bad I can’t let him know I finally figured it out.

I was playing Monopoly, and someone owned a load of properties all clustered together. I said, ‘You’ve got a bit of a monopoly on that part of the board. Hey that’s funny, because we’re playing Monopoly, and you got a…oh, I see now.

That they put measurement stickers next to gas station doors so if a robber is running out of the store you can get a better estimate of their height. I always thought they were just there for something fun to do on road trip stops….

Thought that raw hazelnuts don’t taste good, because they give this weird tingle in your mouth. Found out I had a nut allergy when it suddenly turned from “tingle” to “anaphylaxis” and I ended up in hospital for eating nut chocolate

My mom used to make my sisters and I “belly-buttons” for dinner. I was 27 when I realized that they were actually tortellini, but she knew we were dumb kids and would refuse something named so strange even though they were delicious.

I always thought “You can’t have your cake and eat it, too” was a weird saying because why wouldn’t I be able to eat my freaking slice of cake? It’s my cake.
Nobody was telling me that I can’t have my cake. Turns out they mean you can’t eat the cake while also still retaining it. Once it is eaten, it is gone. An idiom I did not understand until this year. I am 27.

Oh you want a freaking doozy? For YEARS, I did not realize it was Mike Myers playing both Austin Powers AND Dr Evil. I don’t know how I missed it, but it never twigged that it was the same actor. Felt like a right royal twat when that was pointed out to me!

I’m in my fifties. I grew up in a rural area north of New York City, I’m a veteran, I’m reasonably intelligent, reasonably well-traveled.
I’ve been hearing (and repeating this expression on and off for all of my life:
Friend/acquaintance 1: “Hey, man see you soon!” Friend/acquaintance 2: “Not if I see you first.” smirk
It’s just within the last few years that I realized that’s a -almost always joking, kind- jab at Friend/acquaintance 1.
It was so ritualized as a way to say goodnight to a buddy, that it never occurred to me that it meant that the friend would choose to avoid the other person.

For a long time I thought “to bust a nut” meant that you were going to kick a guy in the balls or beat him up. So anytime I was getting worked up or angry talking about some guy I would say ” I’m going to bust his f*cking nut” not knowing the real meaning. Nobody ever said anything but it was always followed by my friends laughing so I assumed it was because I was being dramatic.
Years go by and my coworker is telling me about some rude person he met and I said “you should definitely bust that guy’s nut”, to which he paused and said “do you even know what that means?” Suffice it to say I was extremely embarrassed and horrified when he explained it to me.

When I was little for some reason I hated toast. Just hated it. My parents always tried to make me eat it but I always refused. My grandma decided to try something different. She took toast, cut it up into tiny squares, put some butter on them and called them “Little Pillows.” I ate them all the time. Only now, at 22 years old, did I realize it was just freakin toast.

My boyfriend did not know that his electric toothbrush has a timer on it that goes off at 1 minute and 2 minutes. He actually returned it and got a new one thinking it was broken, since the “timer” is just a brief sort of pause/reduction in the vibration. He would be like “wtf I literally just charged this f*cking thing” thinking that the battery was already dying. One day, and I can’t remember exactly what the conversation was, I brought up how I liked that my toothbrush let me know when I had brushed long enough, and it was like a lightbulb went off in his head and suddenly he put it together that that was what his toothbrush was doing all along.
