It was a very hot day in the forest.

All the birds and animals were tired of the hotsun and were all sleeping.

However, asmall brown monkey couldn't sleepbecause she was very thirsty indeed.

She looked for some water to drink, butcouldn't find it anywhere as it had been avery hot and dry summer.

At last, themonkey saw a big pot.

Was there water init?

She couldn't see any water, but then, itwas very dark in there.

The monkey puther hand into the pot and her long fingersfelt cold water.

What should she do?

Imagine, the water was so near and yet sohard to reach.

The small brown monkey sat down on thestone near the pot and felt thirstier thanever.

She knew that was thehippopotamus's pond nearby.

However,she knew that the water in it was verydirty, but then, she was very thirsty.

Shedecided to go to the pond and when shegot there, she discovered that she couldn'tdrink the water.

It was very dirty.

- I can't drink that.

- she said as she satdown on the bank of the pond crying.

Now the hippopotamus was in the middleof the pond, she saw the monkey andheard her crying.

She heard the monkey'swords and understood that she didn't likeher beautiful water.

She couldn't believeher ears and thought - she didn't like thisproud monkey.

Nevertheless, thehippopotamus had a kind heart and whenshe saw that the monkey was crying, sheswam to the bank and said - There, there.
