This is a story about a servant girl and a dove who met in the forest one day when the girl and her family get attacked by the robbers and she was the only one who survived. She was lost in the forest for a long time with no food and shelter until the dove came and gave everything the girl needed such as food, shelter and clothing but the dove asked a favor to her to do something for the dove. Because the dove gave everything to the girl, she cannot refuse and even she is scared she makes sure that she will fulfill the favor of the dove. As she fulfill her duty and defeated the old woman in the wood she knew that the dove is a prince and they got married and live happily ever after.

        I learned from this story that if someone do good things to you or help you during those times that you need them, do good things to them too in return for their goodness.
