I used to believe that if your arm got cut off it would heal/grow back.

I believed that all of my blood was stored in the calves of my legs.

I used to think that if you poked yourself with a needle you
Would get an infection.

I used to believe there was nothing inside our bodies when I was about 4.

Connie

When I was really young and I heard someone "That hurts my feelings" or something like that I used to think they were talking about the fillings in their teeth.

When, in classroom, teachers told us the diference between right and left, I though their right/left was the opposite of us kids. They were standing in front of us, so their right would be our left, lol, and that confused me. It made sense, because I also had heard adults had more teeth, so I thought that when we became adults, our right and left switched magically.

I used to believe that testicles were called tenticles

When I was a child I believed cavities were things that happened around the time that my mother was a child, and no child had cavities in modern times. This happened because people back then didn't know how to brush their teeth, and in modern times everyone was smarter. I believed it until I was 15, and had my first cavity. I felt really bad and asked the dentist if he did fillings in young people.

I used to think that all words for female private parts started with a B. I thought girls had boobs, a butt, and a 'bagina'. I found this to be a rather helpful way in remembering what girls had, and told a few of my classmates of mixed genders in second grade. They seemed to all agree that it was quite an outstanding coincidence. We called it "the three B's". I wonder when they figured it out...

A bery mistaken girl

I was early to "develop" and also a tomboy. I started getting a chest in the fourth grade and was devastated. I don't know why, but I was convinced that boobs grew at night, so I always wore my bra to bed to try and curb the process. My mom set the record straight after doing laundry and confronting me on why I always needed new bras.

Katie

My grandma had a tooth which was half gold. She told us that we could get a tooth like hers if we didn't stick our tongue in the space our tooth fell out of. I was never successful at that.

Rae

My aunt told me my fingernails would quit growing if I didn't stop chewing on them. I was in my late teens/early twenties before I figured out this wasn't true.
I thought that a woman's private parts were called "China" - imagine my confusion when I learned that fancy dishware and a country were also called China.

Elizabeth

My grandmother told me that if I didn't get my cuticles pushed back that they would grow over my nails. Our neighbor at the time lost his thumb nail and she told me that was what had happened to him. I had great cuticles as a kid.

Stephanie

I told my brother that all girls were born with holes in their ears, and that by keeping earrings in the holes it meant you were proud to be a girl, but some girls let them close up and then got them pierced again. He believed it for most of his childhood.

Michelle

When I was little, a boy at school told me that the white dots that sometimes appear on fingernails were caused by lying. From then on, I was wary of people with injured fingernails. When they developed on my nails occasionally I would worry that everyone would know I had told a lie. I grew up to be very honest!
