box

There is a box. It's just laying there in the middle of the floor. Hanging off the box is a tiny string, and you see that it leads into the box. Because you're too afraid of opening the box, you pull at the string. You pull and you pull and pull, in hope and desperation that you'll find an end, so that there's nothing left in the box... But it never ends. The string keeps coming and your arms keep pulling, you get so tired that you fall to your knees at the floor and pull until you use your last bit of strength until you cannot pull any more.
