## Narrative

The assistant tied a rope to both of the drag ropes to line them back into their lagging, the ropes shifted into place in a sudden motion and he lost his balance. He didn't fall but did slip, because he was standing on top of a plastic sheet that was lying on a mound of dirt and covered by a thin layer of dirt.
