if the roles are mixed up, there will be utter chaos

In a marketplace,

someone will sell flower,

someone rice,

someone fish

and

someone tinklets..

each can sell

only

what he has,

what he knows about,

what he is able to showcase..

if the roles are mixed up, there will be utter chaos..

Even social media posts are like that..

The singer can sing,

the artist can post his pictures,

the writer can display his writing talent,

the smart one can wisecrack

a genuine teacher can impart some knowledge too..

a copyist can cut and paste

and so on

And even when it comes to any particular category like writing, each is just suitable for some subjects alone

..

Dr S Rdhakrishnan may fail in he wrote about quantum mechanics..

and Einstein may not crack Brahmasootram..

Let us not try to make ourselves jacks of all under the sun and the stars

and

become the laughing stocks of all in the milky way..
