Theory:

     The whole earth smelled wet and fresh and even the normally serious–looking people in the village went around with smiles on their faces. The hole in the ground collected the water that fell and around its edges the grass grew a brighter green. Soon buffaloes discovered the grassy spot and as buffaloes want to do, they wallowed in the puddly water, turning the hole into a muddy pit.
     I was not there to see, but I am told that many afternoons did the buffaloes gather and thus with a multitude of hooves trampling the soil, the pit that was once a tiny depression, widened and grew and became a little watering hole.

     “And they all lived happily ever after!” you will say in glee. But that rarely happens in real tales, my dear. There is more to go, so you will have to wait awhile.
Explanation:
 
The whole area smelled fresh and wet. The village people felt happy and there were smiles in their faces, otherwise serious faces. The hole was filled with water and bright green grass grew around the hole. Some buffaloes that came along the way; they saw the grass and water. They ate the grass and drank up the water from the hole. They also rolled about in the water pool that had been formed by the rainwater and the water was filled with mud now. The author had moved away from the place, so he did not see what happened after that. But he says he heard that the buffaloes continued their gathering there for many days. Due to the huge number of sharp feet that crushed the land in the hole, the hole was again widened. Once a small hole, it now looked like a bigger watering hole.

Did the story end here? Did they all live happily ever after? In real stories it doesn't happen that very easily. There is more to the story of the hole, says the author.
