A childhood belief about general

As a child, I refused completely to eat soup. My parents didn't understand why, I wasn't a picky eater normally, but I wouldn't touch a bowl of soup until I was at least 10. I had a good reason though:

I'd seen people eating soup before and, unlike solid food, where you take a bite and you can see that a bit's gone, when you take a spoonful of soup, the rest of the it fills up the part that you took. So, in my tiny brain, I convinced myself that bowls of soup were never ending and unlimited, and, because I was always got told off if I didn't finish most of my food, I'd be forced to sit and eat the same bowl of soup for the rest of my life...
