A ewe was browsing near the edge of a great cliff.  The animal saw a spray of bright berries growing just a little way down and decided that she must have them.  Maneuvering to catch a mouthful as they were tossed by a wind, and caught by a gust herself, the ewe tumbled over the edge.

As she fell, she cried out, “Is there no room for reconsideration?  Am I to be condemned for one errant choice that I now regret?”  But the ewe died all the same.

Moral: You can’t make choices provisionally.
