Why did the monkey make fun of the squirrel? why do you think thework of the squirrel was as important as the work of the monkey?

Monkeys were helping Lord Rama build a bridge over the sea.

They were pulling out the rocks and heavy stones from the mountains and carrying them to the sea. A little squirrel was also carrying little pebbles from the mountains and throwing them into the sea. The squirrel came in the way
of a great monkey and he asked the little thing to get out of his way. The squirrel said that he wanted to work hard and help Rama to build the bridge.

Hearing this the great monkey laughed loudly. He made fun of the squirrel and told his comrades that the little thing was building a bridge with pebbles. And that it was the funniest thing he had ever heard.

The work of the squirrel was as important as the monkey's work.

He had less strength but he worked with devotion and made his best efforts to
help in making the bridge.
