A Short Story …
There once lived a great mathematician in a village outside Ujjain. He was often called by the local king to advice on matters related to the economy. His reputation has spread as far as Taxila in the North and Kanchi in the South. So it hurt him very much when the village headman told him, "You may be a great mathematician who advises the king on economic matters but your son does not know the value of gold or silver."
