bad habits

My older sister really hated it when I sucked my thumb, so she told me that if I kept sucking my thumb way past babyhood, the bad guys from "The Godfather" would break into my room and kill me when I sleep. I never sucked my thumb ever again!

Scared kid

When I was 5 and an adult I knew would get drunk or smoke, my Mom showed me a video to make sure I wouldn't do it when I was older, and the video showed that this weird black stuff accumulated in the lungs of someone who smokes. I thought it was a sludge monster, and that it was going to come alive out of the vial they had it in and eat her, and I thought alcohol was some kind of special drink that made you happy, but if you were greedy and wanted to much happiness, it would make you sleep so that you wouldn't be happy at all.

Safe to say I was a weird kid

I used to believe human mucus was healthy to ingest because it was gross, logically stemming from vegetables being gross, which I got from some tv shows.

I used to bite my nails when I was a child but my brother told me if kept doing that, I couldn't play the guitar because nobody could learn how to play it withouht long nails on the right hand.That's how I stopped this bad habit. Thanks to my older brother. :)

When I was little I was used to picking my nose but one day my mom told me that every time I pick my nose I'm touching my brain and I always believed that if I put a pencil in my nose I could touch my brain.

My father said to me: they are bacteria and eggs when you bite your nails. The eggs will go in your stomach and hatch into worms, eating any form you digested until you starved.
I told mum and she said that he was kidding but I should stop biting my nails.

When I was little I used to pick bogies out of my nose then shove them back In!!
Because my brother told me if you picked your nose your brains would fall out!
I believed him till I was 6yrs old.

I thought cocaine and marijuana were the same thing.
