21 people share their embarassing “Aha!” moments for random things they realized late in life

There’s too much to learn in this life to pick up on all the little things. But there are some “OOOH” moments that are simply too priceless not to laugh at yourself for being slightly dense about.

This Ask Reddit thread is full of “No duh” moments, but don’t go thinking you know everything just yet.

1. Nebakanezzer just uncovered the secret for getting your smoke alarm to stop being a jerk. 

Not sure if this is a feature on all smoke detectors, but finally after five years of owning my house and getting used to grabbing a chair and knocking the batteries out of it, I just hit the test button on the front when it went off while cooking. “Hush mode activated”. It turns it off for fifteen minutes and automatically turns itself back on. It felt like unlocking a secret character in mortal kombat.

2. Wonka_Vision’s mom’s car really needs an oil change by now. 

My mom didn’t know what the oil change light on the dashboard was. She went to her friend (who did a popular morning talk show in Montreal) and asked “why is there a gravy boat light on my dash?” The next morning the entire city knew she’d said that.

3. nukethem’s dad should invest in lint rollers. 

Not me but my dad.

He always likes to look nice and put together. One day before church (I was maybe 14), I asked him if he had a lint roller. He got it for me, and it was absolutely covered in lint. So I ripped off the top sheet. Dad’s eyes widened in shock. “I always thought lint rollers were so expensive for how few times you could use them!” He never knew there were more sheets underneath.

Dad was in his mid fifties then. He hates when I tell that story.

4. detmeng was wasting so much time before vacuuming

You know the plastic hooks on vacuum cleaners that are used to wind the cord around. Well the top hook will spin 180degrees to release the cord, so you don’t have to spend time unwinding. Didn’t realize this till my wife showed me well into my 30’s.

5. Ummm same, Doc_Chickeneater.

In the song “I Saw Mommy Kissing Santa Claus”, it’s daddy dressed as Santa Claus. I didn’t realise til my late 30s.

6. Anonymous7056’s hand was in the cookie jar. 

When I was in first grade, our teacher had these really cool cookie jars. One was a dog that made barking sounds when you opened it, one was a cat that meowed, etc. We all loved those cookie jars.

I realized literally yesterday that they make sound so the adults know when someone’s getting into the cookie jar… It’s fucking genius.

7. Plus, they’re just really fun to slam, ichiatric.

Clapperboards in movies. They’re used as a visual reference to sync the audio and the video together in editing.

8. You and most of the internet too, HarbingerDe.

When I realized that the division sign ‘÷’ is an empty fraction

9. Wait, circuitarteries … WHAT??

The Bagel button on toasters only toast one side of bread, buns, bagels etc.

10. Now I wanna see if my car does that too, MrAndypong.

It took me four years of owning a car to realise I could spray washer fluid onto the rear windshield.

I just assumed it only sprayed the front and I would just occasionally throw a bucket of water on the back if I needed to. Then one day I just noticed an odd symbol on a lever I hadn’t seen before.

Held that mother down for about 10 seconds before a massive gush of liquid burst out the back and changed my life for the better.

11. NotVerySmarts is never shaking hands with this guy again. 

I worked with a guy on a construction site, and it took him 7 months to realize that the porta pottys had urinals in them. He thought that bowl in there was for a sink that they put in the nicer ones.

12. Actually, you may have just stumbled on a life hack, Axle_Goalie.

Just today at the Gym: I forgot my shower sandals, and I was like, “oh sweet, they have disposable slippers, just in case such an event.” Put them on, walked through the change room, used them. They worked well….. I just realized they were showercaps…..

13. LOL’d at this one, MSDMSMPMCRAPAFRRC.

I had no idea that salad spinners were to dry your salad. I thought they were to mix your salad dressing or some shit.

We got one as a wedding gift, so I loaded one up, dumped some dressing in, and spun a ton of the dressing off of the salad. This made me think the product was to apply dressing flavor to all of your salad bits, without dealing with all the calories that can come from overloading on dressing. So naturally I thought it was a total waste of time and money, and tossed it into a cabinet never to be used again.

A year goes by, and I see a comment on Reddit about salad spinners and how they are such a game changer and so worth it, and I thought people were just batshit insane.

Nope. I’m the idiot here. They’re to dry your washed salad bits so you have nice, crisp, not-soggy salad. I had no idea, and the box sure as hell didn’t tell me that.

14. skelebone will never look at arts and crafts the same way again. 

After high school, I was working a temp job in a business remodel. The wood floors had been put in and the contractor had a big roll of paper that he taped down to cover the floor to prevent scuffs and a scrapes while the work continued. One time I touched the roll of paper and noted that it was somewhat sturdier than normal paper and reminded me of craft paper that we used in elementary school. I remembered that as a child,, the teacher always called it (doink — moment of realization) construction paper.

15. Did not see this coming, royalwarhawk.

Since as long as I can remember my mom has kept this creepy doll hung up on the wall in our garage, right next to the door to go in the house. The thing’s a real eye sore, clothes are ugly and it’s just this raggedy thing. So recently, I asked my mom why the hell she keeps this ugly demon doll hung up on the wall and she says, “Really? It holds plastic bags.” And walks up to it and pulls a plastic grocery bag out of its ass. 19 years in that house and I always thought my mom just had weird taste in decoration.

16. Plus, they tell you the name of the town you’re in, skratz17.

water towers are not for storing water. they are to “pressurize a water supply system for the distribution of potable water”. not sure why i thought they were for storing a bunch of water in the sky

17. Never eating anything khamir-ubitch makes. 

“Condensed Soup”.

I always wondered why the cans were smaller yet tasted super salty and were thick. I never took the time to read the instructions about how you’re supposed to add water.

I went 39 years without knowing. One day I finally asked my wife and after she stopped laughing, she explained it to me.

18. cabinjester’s girlfriend is a saint. 

Those travel toothbrushes…

I always carried one on me and always wondered why they made one so tiny. Until one day on vacation with my gf I’m using it and she says “why don’t you use it normally?” She then grabs the casing for the toothbrush and attaches it to the bottom of the brush…

Mindblown

19. Thanks for making me feel super dumb, DadDarrenN06.

Took me an embarrassingly long time to realize that “movie” is referring to a “moving” picture. Old-fashioned term similar to “talkie”

20. Always thought it was an unnecessary accessory for arm sweat, sockfullofshit.

Joggers have sweatbands on their wrists to wipe sweat from their forehead.

Edit: Yes, athletes use them to keep their hands drier, but runners primarily need to keep sweat from running (ha!) into their eyes

21. msbunbury has a hot tip to share at the next baby shower you go to.

That the reason baby vests (onesies) have envelope shoulders is so that when they do a shit that explodes all over the vest, you can remove the vest downwards instead of lifting it over their head and smearing shit all over their head.
