FINE THREAD
A Man ordered some fine thread from a Spinner. The Spinner spun it for him, but the Man said that the thread was not good, and that he wanted the finest thread he could get. The Spinner said:
"If this is not fine enough, take this!" and she pointed to an empty space.
He said that he did not see any. The Spinner said:
"You do not see it, because it is so fine. I do not see it myself."
The Fool was glad, and ordered some more thread of this kind, and paid her for what he got.
