I used to think that when you got some small piece of crud in your eye that it didn't fall or get washed out eventually, it just went into some kind of small repositoiry inside the eye socket and it stayed there your entire life. Not unreasonable for a kid to think that since you hardly ever see what was stuck in your eye even afterwards, do you? I figured if the thing ever filled up then you would really be in for serious eye injury since there would be no place for the next thing that got into your eye to go.
