I have a mechanical pencil with a little cap that guards its eraser. I've slid the cap off so many times that it's pretty loose. So if I'm gesticulating wildly with my pencil in my hand, sometimes it flies off. It's little and plastic and bouncy, so when it flies off it goes places. But I've never lost it, amazingly. It always falls to places that I can get to.

Like today. I was walking down some stairs and it flew off as I was turning a corner. But instead of falling between the stairs way down to the bottom--where it could bounce to who knows where--it started dancing a jig on the flight that I was turning to descend. It's like it doesn't want to get lost, but it wants to be mischievous.
