Hi there !!

Nightingale , was very tired and grew pale day by day , due to the harsh training of the frog.
One day , she was shivering with cold , while practicing .She requested to the frog to let her take rest. But , the frog being heartless , didn't allow her to take rest.She was looking very exhausted.
When she puffed up her lungs to sing , she burst her vein , and gradually ,died !
