"My favorite animal is the mule. He has more horse sense than a horse. He knows when to stop eating ---and he knows when to stop working."
~Harry S. Truman quotes
(With apologies to all my horse friends.)
I love the mules, though I would much prefer that they were on a farm frolicking (do mules frolick?) rather than standing in the hot sun waiting for drivers to persuade tourists to take an over priced carriage ride. They always look so sad just standing there patiently.
