|
After a hearty lunch, my parents and my younger sisters lay down for an afternoon nap and I settled down with a storybook. The quiet afternoon presented the perfect backdrop for reading an adventure story. The silence was occasionally broken by the sound of my family snoring, the intermittent chirping of house sparrows, the harsh cawing of a crow the shrill call of a kite flying high above the ground. Minutes ticked by. I became deeply absorbed in the book. Suddenly, 1 heard a group of street dogs barking furiously in the distance. I chose to ignore the commotion thinking that the pack of dogs might have cornered a hapless pig. But soon, the barking became louder and more aggressive and the alarmed cawing of a flock of crows added to the cacophony. I also heard the disturbance approaching closer. Curiosity got the better of me. Leaving the book aside, I rushed to the veranda to see what was going on. |

The sun was now ascending the sky, blazing on his ledge that faced the south. He felt the heat because he had not eaten since the previous nightfall. He stepped slowly out to the brink of the ledge, and standing on one leg with the other leg hidden under his wing, he closed one eye, then the other, and pretended to be falling asleep. Still, they took no notice of him. He saw his two brothers and his sister lying on the plateau dozing with their heads sunk into their necks. His father was preening the feathers on his white back. Only his mother was looking at him. She was standing on a little high hump on the plateau, her white breast thrust forward. Now and again, she tore at a piece of fish that lay at her feet and then scrapped each side of her beak on the rock. The sight of the food maddened him. How he loved to tear food that way, scrapping his beak now and again to whet it. |
