What is ‘obvious’ to you and me might not be clear to someone else. And vice versa! Common sense isn’t all that common. Not to mention that all of us, no matter our education, have gaps in our knowledge that we’re not aware of. It takes quite a bit of guts and tons of humility to admit that.

Members of the r/AskReddit online community recently opened up about the ‘really obvious’ things they only just realized. Scroll down for a good laugh, as well as a reminder that we’re not so different when it comes to our info blindspots, after all.

Common Sense Isn’t All That Common: 45 ‘Obvious’ Things People Only Just Learned Learned I was allergic to latex from talking to my friend. She told me that since I’m allergic to some citrus I may be allergic to latex and asked me if condoms bothered me. I responded and said yes but they bother everyone who uses them.

That’s how I learned that burning and itching and a road rash are not normal after coitus with a condom. ? (I’m 26).

Common Sense Isn’t All That Common: 45 ‘Obvious’ Things People Only Just Learned I learned where "Pulling out all the stops" came from a couple of years ago (watching a documentary on Interstellar's music).

It's from playing organs...air is blown thru the organ's pipes to play notes - and you have "stops" in there if you don't want a particular pipe to play. So when you pull out all the stops, you get all the pipes playing...

Common Sense Isn’t All That Common: 45 ‘Obvious’ Things People Only Just Learned I was like 25 when I found out the jugs of washer fluid outside the gas station aren’t free. I was walking out of the gas station with a buddy one day, grabbed a jug of washer fluid, and he asked me “did you just steal that?” And I was like “No, dude, it’s free”. It’s not, I stole washer fluid for nearly ten years of driving and no one ever said anything to me about it.

I recently realized that “Howdy” is short for “How do you do?”

I actually just googled it, and it’s technically short for “How do ye?” However, my realization still makes sense.

I was 39 when I realised the pointy bit on a the lid of a tube of something, for example tomato puree.. Was for braking the foil seal. For years I used a fork to break the seal until I watched someone remove the lid , turn it around and place it over the seal. Mind blown.

Common Sense Isn’t All That Common: 45 ‘Obvious’ Things People Only Just Learned I'm Norwegian, and was at least thirty before I realized that the tomatoes crossing the road schoolyard joke (two tomatoes cross the road, one gets run over, the other says "Come on, catch up") has, in what I assume is the original English, a punchline. Well, for a schoolyard joke, anyway.

Norwegian kids tell the same joke, but there's no catch up/ketchup pun in Norwegian, so they just tell a joke where the squashed tomato is now ketchup. At some point a kid who knew enough English to have heard the joke but not enough for the pun told it to younger kids, who assumed it was funny because an older kid was telling it, and it has been repeated between children for generations.

Common Sense Isn’t All That Common: 45 ‘Obvious’ Things People Only Just Learned I grew up in Poland. When a person was arrested on a crime that was publicized, the media will only list their first name and the first initial of last name, to protect their identity before conviction, e.g. Peter G. My friend thought that all criminals had one letter last names and he was surprised the police wouldn’t just go all Minority Report on them and arrest all people with one letter last names.

I am not responsible for other people's lives. Feels a little better accepting that I don't have to stress too much over supporting my family. I shouldn't feel too overwhelmed to the point of having suicidal ideations just from the stress alone. Edit : No, I don't have kids. I'm single, been supporting my family (parents, siblings) for 10 years.

I only realized recently, at 40 years old, that a "fortnight" is called that because it's like "fourteen nights"...

I think because I always remembered it as two weeks, and not 14 days.

That sometimes things are just the way they are, you can't change the situation you're in, only your actions and your emotions and how you react to them.
I guess I realized that certain situations sometimes feel unfair or are not favourable to your needs and you have to find happiness in the best way you can and live your life. Sometimes you gotta make sacrificies because that's the only option.

I know "felix" is the Latin word for "happy," but only recently did I discover the name Felix is also known to mean "lucky."

Now I'm getting the irony of naming a *black cat* "Felix the Cat."

(For those who don't know, Felix is an old cartoon, and there's a superstition that a black cat crossing your path is very *un*lucky.)

Colonoscopies aren’t just for looking for cancer and other issues. It’s preventative for cancer because they remove the polyps where it starts. I’m pretty up on medical stuff, didn’t know that.

I'm 50 ish. For the last couple years I kept feeling that I'm getting close to retirement and I'm only going to have a few years to do what I want... Then I realized I could only be halfway there! What if I live till I'm 90? That's 40 more years! I have time to do absolutely anything I want to! It was just this crazy sort of epiphany that went you're looking at this all wrong! Life isn't over at 60 or 65, you still have a lot of time!
