For some reason I always associated numbers with different shades of light and dark. For example numbers 1-5 are kind of dark and 6,7,8,9,are light numbers. The further you go down the line they gradually get lighter and darker. I have no idea where I got this but till this day, I still see numbers that way.

- The highest of all numbers was "a finnety."— Becky
- i used to belive that 1 to 10 were the only numbers and all others were made up.....— Eric
- I used to believe there was a limit on the numbers you could count — Carmen
- I used to be terrified of the numbers 18 and 19. I think I thought that when you turned 18 or 19, you die.— Emmy
