We all have an "ah-ha" moment every now and then but have you ever stopped and realized something so obvious you felt silly for not knowing about it much, much sooner? If you have, you're not alone. These people share the really obvious things they didn't figure out until embarrassingly late in their lives. Basically, we're just a whole bunch of idiots wandering around trying not to bump into each other.

#2 Identical Friends

So there are these two girls. They sit opposite me at lunch. I'd say perhaps an hour of time a day, these girls are sat directly in front of me. Five hours a week, twenty-odd weeks before I'd noticed. So a hundred hours of being next to these two girls... "Oh my god. You two are identical twins."

#7 Light Switch

We had a light switch in my house that I did not notice for ten years. I was fascinated by it for a week after I discovered it.

#9 Mysterious Bathtub

I've been living in this house for a year now. There is a button in my bathroom that will fill up the bathtub automatically. I don't even have to turn the taps. I'm still too scared to play with the toilet controls. I think some of them are for ladies only; I pressed the pink button and it washed my undercarriage.

#14 Soduko Tricks

This is one I'm particularly ashamed of. Worst of all it was well before my drug days, so I can't blame it on that. But I got the sodoku demo cartridge for the original DS and played the game quite frequently, always struggling a bit with each game. Sodoku is a great game. I never needed to buy it because the demo version was giving me hundreds of hours of fun in itself!

Of course, the demo was always just the one game over and over, for years I would play it thinking I was getting a new game each time. I don't know what is wrong with me, but I just never noticed. And I struggled with each game as if I were playing it for the first time. I should probably have mentioned this to my doctor.

#15 IHOP

IHOP = International House of Pancakes I actually thought they were two different chains. "Why are we pulling into the IHOP parking lot? I thought we were going to the International Hou-- OH MY GOD." I was all excited, too, 'cause I thought I'd never been to an International House of Pancakes before.

#19 Chick-fil-a

Up until about a month ago, I thought Chik-fil-a was pronounced "chik-fill-ah." When someone pronounced it correctly I literally slapped my forehead... "Of course... as in fillet."

#21 Visa Card

When I was a teenager I thought that Visa was forcing people from other countries to get a credit card if they wanted to stay in the U.S.

#23 Mattress Double Meaning

For many years, I didn't get the double meaning from the Sleepy's mattress commercials.

Trust Sleepy's......for the rest of your life!

Then one day I was driving with my wife, and the commercial came on. I said, "Why would I want a Sleepy's mattress for the rest of my life? Aren't you supposed to replace them every 10 years or so?" She patiently explained the double meaning, and also that I'm an idiot. Which is apparently true given the evidence.

#29 Hidden Door Handle

My mom and dad were looking at a house for sale. They were being shown around inside by the man and woman who currently lived there. While being shown the dining room, the woman showed my mother the nice sliding doors that hid inside the wall. My mother wanting to see if the doors rails still worked properly opened the doors the full way (so the door was completely hidden inside the wall). The woman jumps forward saying "Oh no! You've pushed them too far! This always happens to us with new people! The doors are too far in the wall, and it takes us forever to pry is out cause we can't reach it."

My mother looks at her quite shocked (as my then family home had the same style of door) and grabbed the hidden handle on the door and easily pulled the door out. The woman and her husband stood there in shock and later explained that they used to get in fights over this door for years. My parents laughed and left. They never bought the house.

#30 Afternoon

A few weeks ago I, for the first time, understood why afternoon is called afterNOON. I felt so dumb, and my roommates weren't impressed.

#31 Apartment Appliances

After looking at dozens of places and much careful consideration, I moved into my beautiful, perfect, beachfront apartment one month ago. Two weeks back, I went to make cookies. No oven.

#32 Creepy Tuxedo Town

Got lost driving upstate NY by myself once, at 1AM. I took a wrong turn trying to get to Route 17, and wound up in a little town that clearly wasn't where I wanted to be. It was a bit foggy and my phone (EVO) was constantly rebooting and I didn't have a GPS. Nothing was open. Streets were completely vacant. No signs of life at all. It was a bit creepy.

It got creepier when as I was driving around trying to find a way back to the highway I noticed that there were tuxedo shops everywhere. It seemed like every other shop was a tuxedo shop. Why would a town need so many tuxedo shops? It got to the point where I was in a near panic state. I started driving faster through this little town, counting tuxedo shops. I stopped counting at 15 and concluded I was the protagonist in a twilight zone episode.

Panic set in. I drove. Anywhere. Anywhere where there isn't a tuxedo shop. Turn around and just keep going. Don't stop. Finally, I see the highway. I drive the wrong way up the ramp, cross over the median and get the hell out of there. Traffic rules be damned I was going to be trapped in some odd little town seemingly in the middle of nowhere that consisted of tuxedo shops. I was picturing every person coming out wearing tuxedos trying to get me to stay. Forever.

I finally escaped and got to my destination. I didn't tell a soul about it for about a year. One day my wife and I are driving the same route and I tell her about the strange little town where all the shops were tuxedo shops... Turns out I was in Tuxedo, NY.

#33 Catching Pokemon

I used to play Pokemon Red as a little boy. I couldn't read English since my native language is Dutch therefore I skipped the tutorial and didn't know I could CATCH the Pokemon. I played it for over two years with just one Pokemon until a friend told me I could use a Poke-ball to catch them.

#40 Ticket Number

Ok, so once or twice a month we order takeout from a burger shop near our house. Every time I call up and make an order, at the end of the conversation, whoever I'm talking to usually says something along the lines of "Okay that'll be 15 minutes and it's 42." The number at the end changes every time, and I assumed they were telling me how much it was. I'd do the math on my way there and get confused because it was always wrong.

One day, after about six months of this happening, and having ordered a fair bit of food, the young boy said, "Ok thanks, that's 116." I thought they can't be serious, we didn't order that much! I went down and it was about 50 bucks. I asked why they always quote the wrong price, and the lady said loudly "Oh darling that's not the price that's your ticket number!" prompting laughs from everyone in the store.

#43 Hey Jude

For a long, long period of time, I thought that the famous Beatles song started "Hey Jew...." It always struck me as very odd and I couldn't, no matter how hard I tried, see how it fit in with the rest of the song. However, for some weird reason I never checked out the lyrics. Across the Universe was a huge "Oooh, now I get it" moment for me.

#44 Piglet is a Piglet

Despite Piglet being called Piglet I assumed he was a mouse for most of my childhood/teenage years. Turns out he's a piglet and that's why he's called Piglet.
