Avoiding Criticism

Nasrudin and his son were travelling with their donkey. Nasrudin preferred to walk while his son rode the donkey. Soon they passed a group of bystanders, and one of them said, "This boy is so selfish. He is riding on a donkey while his poor old father is forced to walk alongside."
"This is so disrespectful," said another man. "What a horrible and spoiled child!"
Nasrudin and his son felt embarrassed, so they changed places — this time Nasrudin rode the donkey while his son walked. "I hope I am doing the right thing now," he said to himself.
Soon they passed another group of people. Seeing them, one of them exclaimed, "The poor young boy has to walk while his selfish father is riding the donkey! He is a heartless parent!"
Nasrudin was upset to hear this. "I wish people would mind their own business," he said.
Since he wanted to avoid any further comments, he decided that both he and his son would ride the donkey at the same time. As they both rode, they passed another group of people. "That man and his son are so cruel," one bystander commented. "They are forcing that poor donkey to bear the weight of two people. They should be put in jail for this act."
Nasrudin heard this and told his son, "The only way we can avoid people's comments is that we both walk."
"I suppose you are right," the son replied.
"I promise, nobody will be able to say anything to us as we are doing the right thing this time," said Nasrudin happily.
So they got off the donkey and continued on foot. But as they passed another group of people, they heard them laughing. "These people are so stupid that both of them are walking in this heat and neither of them is riding the donkey," they said. 'What foolish people they are!"

Ans: Nasrudin and his son were travelling with their donkey. Nasrudin preferred to walk while his son rode the donkey. Soon they passed a group of bystanders, and one of them said that the boy was so selfish. He was riding on a donkey while his poor old father wass forced to walk alongside.
Another man exclaimed that was so disrespectful and he was a horrible and spoiled child.
Nasrudin and his son felt embarrassed, so they changed places — this time Nasrudin rode the donkey while his son walked. he said and hoped that he was doing the right thing then.
Soon they passed another group of people. Seeing them, one of them exclaimed that the poor young boy had to walk while his selfish father was riding the donkey. He was a heartless parent.
Nasrudin was upset to hear this. He wished that people would mind their own business.
Since he wanted to avoid any further comments, he decided that both he and his son would ride the donkey at the same time. As they both rode, they passed another group of people. One bystander commented that man and his son were so cruel. they were forcing that poor donkey to bear the weight of two people. They should be put in jail for that act.
Nasrudin heard this and told his son that the only way they could avoid people's comments was that they both walked.
The son replied hopefully that he was right.
Nasrudin happily promised that nobody would be able to say anything to them as they were doing the right thing that time.
So they got off the donkey and continued on foot. But as they passed another group of people, they heard them laughing. They said that those people were so stupid that both of them were walking in that heat and neither of them was riding the donkey. They exclaimed that they were foolish people.
