A parable

Once upon a time, there was a student who went to a prestigious institute in a village in China. The student was from a very poor family and could not afford both living expenses and food. He rented a small dark room located on top of a restaurant and only ever ate plain rice everyday. One day, a friend from his village visited him and learned who he lived. His friend could not believe it, and asked him, "are you not sick of eating plain rice everyday?" The student replied "not really, because I have a trick". The student explained that timed his meals so that he ate his rice when the restaurant owner cooked for his customers. The smell of the food cooking below flavoured his plain rice. He explained to his friend, it was like having a different meal time.  The restaurant owner overheard the student's conversation and was furious. He was made at the fact that this student was using his smells for no cost and demanded that the student repay for all the food he has stolen.  The judge in the court was known as the fairest judge in all of China and promised to hear both of their cases. The restaurant owner angrily explained that the student was stealing food from the good people who payed at his restaurant. The student said he was not stealing but only trying to flavour his rice as he could not afford to eat anything else. After hearing their cases, the judge ruled that the student was indeed guilty of stealing. He therefore told the student to take out all of his money in order to repay what he had stole. The poor student emptied all of his money from his pockets,  the amount was so little that it only fit in one hand. As the restaurant owner approached, the judge said "hold on!" He commanded the student to pass the money from one hand to another. The student did and the money made clinking sounds as it passed from one hand to another. And then the judge said "all is repaid". The judge then dismissed the student and the restaurant owner. The owner was confused and demanded an explanation from the judge. The judge explained that the student paid for the smell of the owner's food, with the sound of his money.
