Time Goes On......
As the sun sets  Sumana wakes
up. What a lovely evening! 
She washes her face fast in 2 hours
 and runs out. She goes straight
to the bird's nest. She has been watching the
eggs for the last few months .
She was waiting for the baby birds to come
out. But before she can blink her eyes, in a
week  a cat jumps on to the tree.
The mother bird cries loudly and Sumana rushes
to shoo away the cat. As the cat jumps, it hits
the big green mango. Dhum! ...
Dhum!
... In two days  it is on the ground ! Oh, how sad! The mango is
still not fully ripe. It needed one more year  to become sweet.
Suddenly Sumana's sister calls out — Are you still not hungry? Has your stomach
clock gone to sleep? Come and eat hot upma for dinner .
