There was once a man, who was a talented carpenter. He just had to touch a piece of wood to know how it could be worked, how it might split, how it would behave under his tools. He started off as a little village carpenter, making furniture and doors for the people of his village.
One day, he built a chair for a local dignitary. The dignitary asked if he could paint it, too.
“Oh no,” said the carpenter. “I’m not a painter. I only work with wood. I have built you the best chair I can, and I wouldn’t want to spoil it. If you want it painting, find a painter to do it.”
The dignitary took his chair away, unhappy. Many visitors to his home saw the chair, though, and were very impressed. Some of them came back to the village to visit the carpenter themselves, when they wanted furniture making.
