I was pondering writing. 

Then started thinking of people writing about other people writing. 

That forces me to think about the teacher that teaches those writers how to write about writing about writers. 

What are you even writing about with that?

Now I am writing about writers who write about other writers and thinking about writers that write about other people writing about other people. 

Why do writers write about other writers when they should be writing their own works?

Who reads that dribble and what is the point, except to criticize or assist? Unless to continue with the work.
