The miller, his son and the ass (if you try to please everyone you will achieve nothing)

A miller and his son were taking their ass to sell at market, when they passed a group of girls, who laughed at how foolish the miller was to have an ass and yet be walking. So the miller put his son on the ass. Further down the road they passed some old people who scolded the miller for allowing his young son to ride, when he should be riding himself. So the miller removed his son and mounted the ass himself. Further along the road, they passed some travellers who said that if he wanted to sell the ass the two of them should carry him or he’d be exhausted and worthless. So the miller and his son bound the ass’s legs to a pole and carried him. When they approached the town the people laughed at the sight of them, so loud that the noise frightened the ass, who kicked out and fell off a bridge into the river and drowned. The embarrassed miller and son went home with nothing, save the lesson that you will achieve nothing by trying to please everyone.
