When i was a child, i believed autopilot really worked like in the movie Airplane, that it was an inflatable dummy.
That a blowjob involved the act of physically blowing air on the penis. When I found out it actually involved sucking, I was like, "Oooh...yeah that sounds much more pleasurable."
In my language the expression is "jemandem einen blasen" (to blow one to someone) and I remember reading a long time ago about a story where a teenage girl (?) actually injured her boyfriend when she blew into the penis. Seems not to be a very good idea.
I thought our eyes worked by projecting some kind of energy beam that scanned objects, like how Superman's X-ray vision is sometimes drawn.
When I was little, I thought that "cash back" meant that the clerk literally just handed you money out of the register if you wanted it.
I assumed that most people were honest and only took the cash if they needed it. I didn't know that it came out of your checking account lol.
It's actually surprising how many people have believed this.
I remember believing this as well but specifically you had to kiss in a bed.
I scraped my knee and thought that putting skin-coloured paint on it would heal it
When I was a young lad I thought milk was cow pee and was super confused by the world.
My parents didn't specifically tell me if Santa Clause was real or make-believe. They wanted me to come to my own conclusion, I guess. My dad is a rationalist person, and my mom's from a culture that doesn't traditionally celebrate Christmas.
So what I believed was that the appearance of presents on Christmas was an unsolved mystery, and Santa Clause was just a hypothesis to explain it.
I suspected the real explanation probably involved the tree working as an antenna for some kind of cosmic energy that triggered the appearance of presents. Perhaps in ancient and more superstitious times they discovered this phenomenon by accident and continued to put up the tree ever since.
That adults had it figured out.
That average people actually care about anything but themselves.
That there is justice in the world.
I thought every song on the radio was being performed live somewhere
I used to think radio stations were run from inside of the broadcasting tower, like how the CN Tower and Space Needle have decks near the top.
When adults said things like "In this day and age, nobody says please and thankyou any more", I misinterpreted "this day and age" as "The Stayan Age", which was our current age, which obviously followed on from Bronze Age, Iron Age etc.
They are if you think the exact opposite. Everyone has their niche, no one is a jack of all knowledge
I used to think that there was a country called Cyclopedia, that was full of all kinds of fascinating things. I had a book all about it called "In Cyclopedia".
Most humans have good ethics and beliefs. The more I grow, the more I'm disappointed in our society.
The "dogs are boys, cats are girls" one is a very common answer to this question on reddit.
