The favor the elephant asked of the man was to let him put his trunk inside the man's hut to keep it dry from the rain.
One rainy day, an elephant was walking through the forest when it came across a man's hut. The rain was coming down in sheets, and the elephant's trunk was getting soaked. He knew that if his trunk got too wet, it would become very heavy and difficult to use.
So, the elephant went to the man's hut and asked him if he could please put his trunk inside the hut to keep it dry. The man was surprised by the request, but he was kind and agreed to let the elephant do so.
The elephant was very grateful for the man's kindness. He stayed in the hut for a while until the rain stopped. Then, he thanked the man and went on his way.
The man was happy to help the elephant. He knew that the elephant was a big and powerful animal, but he also knew that he was kind and gentle. He was glad to be able to help him out in a time of need.
