I always thought cigarettes contain tar, as in the substance asphalt on the road is made from. It always felt weird to me, why would they put it in the cigarettes but I figured maybe they need it so the tobacco doesn't fall out or something.

Old people were always old

The crust on bread had more nutrients than the center. My dad didn’t want to cut my crusts off lol.

My uncle always swapped the words breast and best so my cousin mixes them up sometimes to this day. He said ‘breast friend’ at his brother’s wedding

when i was a child, i was told that i would get worms if i ate raw brown sugar. i believed this for quite some time at least until i was 12.

That there was a disembodied head that lived in the toilet at night.

That god(s) exist(s).

That I could dig to China

When I was six years old or so, my sister called me a "cosweb" and told me it was the worst thing ever. I completely believed her for a long time.

That, despite my feelings and emotions at the time, I would never be a girl. So, that was a fucking lie.

That all large salty bodies of water were called "the mediterranean sea."

Trees make wind because whenever there was wind, they moved.

That the Mormon god was totally real

I do not know where I got this from, but I thought all dogs were male and all cats were female. I thought this while I had a dog named Betsy and a cat named Sebastian.

If that's not bad enough on its own, I think I was in first or second grade when I learned the surprising truth. I wasn't a dumb kid, either. I learned to read when I was about 3.5 yrs old and started 1st grade as a 5 yr old.

I'm now in my 70s and I still can't figure out where I got that from!

I thought the moon had a face. Like, as a kid, I would look at the moon and in my mind the craters formed what clearly seemed as two eyes and a mouth.

That Africa was largely unexplored by humans and mostly unpopulated

I thought chocolate was a color

You can accomplish anything if you put your mind to it and try hard enough.

That if we didn't have enough money we could just go to the ATM and get more.

Also, when I was very young, I apparently spent too long in the toilet once and one of my parents (don't recall which) asked me if I'd fallen down the hole.
It took me shitting myself at school months later for them to find out that I'd been terrified of falling into the toilet (and avoiding using it as much and for as long as I could, or, in that particular occasion, longer) since that day.
(I was small but not that small, obviously, but kids can be surprisingly dumb for how surprisingly smart they are.)

Hiccups mean youre growing.

Thanks parents.

The big stereo speakers in my living room contained tiny orchestras

Einstein said that if you move close to the speed of light, you'll go forward in time. Therefore, I thought, if you go backwards at close to the speed of light, you'll go backwards in time.
