Once, a father and son were travelling. The father was sitting on a donkey whilst the son was pulling the reigns of the donkey. They decided to take turns riding the donkey. One hour the father would ride and the next hour the son would ride. They suddenly came upon a village when the people shouted out to the father, “Don’t you have brains? You, a big dunce on the donkey while your little son is pulling the donkey!” The father immediately jumped down and put the son on the donkey and they carried on travelling.
