Man, I hate it when you get all comfortable while doing your hw, then you get distracted, and when your attention falls back on the hw, your pencil's disappeared. Then you gotta get up and go find another pencil. And it's super-annoying when you realize after you've found another writing utensil that your original one was in a really stupid place. (e.g. under where your butt was, haha) That seems to happen to me a lot, and then I can never seem to get quite as comfortable again as I was before the whole incident.
