There was a bully who liked to pass where a plowman was working in the fields behind his mule all day and yell at him to work harder, and insult him, and criticize what he was doing, and hurl all sorts of rude remarks his way.  But the plowman just ignored him and went on working, busy with his tasks.  Finally, one afternoon, when the bully was being especially rude, the plowman could take it no longer and looked up and said, "Why don't you try to do what I'm doing, if you think it's so easy?  Or are you too weak?"  "I could," the bully yelled back, "but I choose not to.  It doesn't mean I'm not strong enough to do the work though."  "Well, then," the plowman said, wiping his brow, "let's see."  Then he suggested that they each take turns pulling against his mule, which was known to be the strongest for many miles around.  The bully agreed to this, and in due course the plowman unhooked the animal from the plow and took his place before it.  He pulled with all his might on the beast's tether, and, as was his type's contrary way, the mule pulled in the opposite direction.  Finally, after great struggle, the plowman managed to inch the mule a few feet towards him.  "There," he said, satisfied with his effort, but the bully simply laughed and pushed him aside.  "Now you'll see real strength," he said, taking up the line.  He pulled and pulled, but he could not seem to get the animal to budge.  Just then, when the effort seemed most futile, the mule, realizing that it was not his master who was pulling, simply gave up and allowed himself to be moved freely.  This caused the bully to fall flat on the ground, breaking several teeth.  "Well, I guess you're the stronger," the plowman conceded, "and I also guess that you won't be bothering me with your noise for awhile."

Mind your own business, and don't pick fights where none are warranted.
