There was a camel who lived at the edge of an oasis. Once, when it fell ill, all its friends and relatives came to visit it.
As it was a long journey in the desert, each of them halted to take rest and ate the grass that grew along the oasis.
When the sick camel recovered from  illness and looked around for some grass to eat, it discovered that there was none left. Its friends and relatives had eaten away everything. It found itself helpless, and having no alternative, he set off again to find another oasis.

Moral : Be considerate to a sick friend or a relative.
