grown-ups

I used to think ballerinas walked on their toes all the time, before realizing they were specially trained to dance that way!

I used to think doctors were male and nurses were female.

I thought my grandad would get older, so I asked him 'What do you want to be when you're older?'.

I used to think Jane Austen was related to the Bronte sisters, maybe like their cousin or step/half sister.

i believe that if im born in december im older then people born in may

I used to think bumper cars or dodgems were for kids under 16 to take driving lessons, especially if they had their mum or dad with them! I'm glad I never drove one with my dad, and I don't drive now as an adult, or he'd probably shout at me in the passenger seat about being a rubbish driver, knowing what dads are often like with their daughters!

I thought the term maiden name actually applied to women who were maidens.

When I was a child I thought there was a person inside the ATM

My mother has a neurological condition where she has trouble concentrating on multiple things at once (not ADHD).
When I was a kid, I thought that this was an "adult" thing and that as I got older, I'd eventually lose my ability to concentrate on multiple things at once.
As I grew to be a teenager, I thought that I was the weird one and had some sort of mutation or other that allowed me to focus on more than one thing at a time.
It was only when I was about 16 that I learnt that having trouble focusing on multiple things at once was the exception, not the rule.

I used to think stage makeup was like ordinary makeup, and that people would do things like draw on themselves with lipstick to look like blood or use eyebrow or eyeliner pencils to give themselves spots. It does sound fun.

I thought "deployed" meant "fired".

When I was eight or so, I was at the mall with my mother and got bored, so I looked through the greeting cards for something to do.

One of them had a message "you're not old until the fat lady sings" and when I opened it, it had an illustration of a large woman singing. I was worried that I'd then turn into an old woman.

When I was a kid I used think my father ever was right and other people was stupid.

When I first heard the word "lumberjack", I thought it was "Numberjack" like the TV show The Numberjacks. When I was corrected, I thought a lumberjack was a dude named Jack who lumbered around.

When I was about 6 years old, I believed that a man wasn't allowed to get married if he hadn't been in the Army.

When I was a child I used to believe children were being brought by stork.
