When I was in Kindergarten, I was wholly and completely convinced that thirty was the highest number. NO ONE got in the way of that no matter what they said, no matter how smart I believed they were. Thirty was the highest number in the world, a big intimidating, staggering number. I used to be very, very mad at my teachers who told me otherwise. I screamed at one of them at the top of my lungs (possibly more, I only remember one in particular). My friends back then even knew. They would say "well there's forty and fifty and sixty ...", and, let's make a long story short - they weren't my friends much longer.
