What according to you, is the story about? Consider the following;
(i) How the world began.
(ii) Why everyone should do his/her share of work seriously.
(iii) How animals are important to humans.
(iv) How the camel got his hump.
In my opinion, the story tell us that everyone of us should do his/her share of work seriously. If we do not do our work seriously, we are sure to get a hump on our back. Idleness leads to deformity.
