A bird was confined in a cage outside a window.She often sang at night when all other birds were asleep.
One night a bat came.He asked the bird why she was silent by day and sang only at night.
The bird answered,"Last year when I was singing in the daytime,a bird catcher heard my voice and caught me in his net.Since then I have never sung by day.''
The bat replied,"But it is useless to do this now that you have become a prisoner.'' Then he hlew away.
