Theory:

     “Certainly, as many as you like and some for your wife too,” said the monkey. “Do come again. I’m rather lonely here”.
 
     The crocodile visited the monkey regularly and ate the fruits which his host threw down. He took some home for his wife. The monkey and the crocodile were now the best of friends. They talked and were never tired of talking. They talked about birds and animals, about the villages nearby and the difficulties villagers faced in raising good crops for lack of rain.
Explanation:
 
The monkey spoke to the crocodile with great pleasure and satisfaction. All these days, the monkey was looking for someone to talk and share its food since it felt sad while alone. It replied to the crocodile in a pleasant voice. It accepted to offer food to the crocodile and its wife as much as possible. The monkey also asked the crocodile to revisit as it is alone in that place.

The crocodile started to visit the money as requested by its host, and the monkey also helped the crocodile by offering fruits. The crocodile shared the food given by the monkey to his wife as well. After some time, this became a routine for both the crocodile and the monkey to share food and converse. Though their discussion went for long hours, it never made them tired but happy and entertaining. The discussion between the crocodile and the monkey involves many things. They discussed the birds and animals, the villages nearby, and the difficulties villagers faced in raising good crops due to lack of rain.
