An ant went to the river to drink some water. But while drinking water, the ant fell in the river. The ant was crying for help. When suddenly a dove who was sitting on a nearby tree saw the ant struggling for life. The dove quickly plucked a leaf from a tree and threw it down in the river. The ant climbed the leaf immediately and thanked the dove for saving it's life.
The ant thought, "Dear God, please bless the dove for saving my life. If I do get a chance, I'll repay the dove for it's kind deed."
Several days later, the ant saw a hunter spreading a net in order to catch the dove.
The ant remembered how the dove had saved her life and thought maybe this is a chance from the Almighty to repay the dove. And then without wasting another moment the ant bit the hunter's foot very very hard.
The hunter screamed in pain and dropped his net. Hearing the noise, the dove quickly flew away.
MORAL :- One good deed deserves another.
