A butcher, sells meat.
It is his bread and butter. It is what he is skilled and experienced at doing. He knows exactly what to do, where to makes the chops, and executes it with utmost skill. He has always made his living selling meat, doing what he does best. Sometimes, people name him as the best butcher the town has ever seen. He is respected, a little overrated perhaps.
One day, at the point when demand for meat is at its peak, at the point when it matters most to the people that the best butcher provided them with the best service, the butcher quit. Instead, he made a switch to selling fish and becoming a fishmonger. Nobody could understand his decision, as to why he wanted to sell fish. To make things worse, the replacement butcher could not carry out his job properly, causing much discontent. The original butcher himself could not even sell fish properly, as he was too used to selling meat and the skills which were involved in it. There were no winners in this situation.
Finally, the people convinced the butcher to reverting to what he did best, selling meat. They had to persuade him to not sell fish anymore. Things were better now, and it was to the benefit of everybody. Things were better now, hopefully.
To most, the matter was resolved.
To some, the butcher's acts would remain their minds forever. Perhaps, it therefore cast a different light.
