Once upon a time, an old country doctor was visiting a sick patient on his farm. As he was leaving, he happened to see an old, boarded up well, which piqued his curiosity. Naturally, he wondered why it was boarded up, so he went over to remove the obstruction. Alas, he accidentally fell in. For two days, the farmer and his friends tried to get the good doctor out, finally succeeding as the sun was setting. The curious doctor had learnedaval uable lessonand, never again let his curiosity run away with him.
Moral:
The doctor should have tended to the sick, and left the well alone.
