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.
The tale tells us, in my view, that each of us should seriously do his / her share of the job. We're sure to get a hump on our back if we don't do our job seriously. Idleness results in deformation.
