A thread

The girl picked up a clipboard, it was blank. She wrote "sign here" and handed it to pinkie.

"Ooh!" She cried and signed it. This of course was bullshit. The girl put it down on the edge of the desk, purposely catching a loose thread on pinkies top. She put a book on top to hold it.

"All done" she said. Pinkie jumped in delighted and skipped off, the thread unwinding...
