You are surely familiar with the story–a miller and his son take their ass to the market to sell it and along the way they meet several individuals or groups of people who comment or criticize them on their trip. The miller and his son adjust their journey according the comments or criticisms: when told they should be riding the ass, the miller puts his son on the ass; when criticized for not respecting the aged, the miller replaces himself on the ass; when criticized for being lazy, the miller then lets his son ride behind him; and when told they could more easily carry the ass rather than have it carry them, they proceed to tie the legs of the beast and haul it around with a pole. As they cross a bridge near the town, the townsfolk laugh at the sight before them and the commotion frightens the ass which breaks free of the restraints and tumbles into the river.
The obvious moral of the story is that if you try to please everyone, you end up pleasing no one.
