You must have heard the story of the man, his son and a donkey: if not, today is your day; I will tell you all about it.
The folktale goes something like this.
One day a man and his son and their donkey were going to the market. As they walked along they met a group of people who laughed at them and asked why they were not making use of the donkey. So the man put his son on the donkey.
