Bloodline

Humans have an inherent inclination towards segregation and classification. All of us do it, whether consciously or otherwise.
Ustad Zakir Husain had once said that though he didn't feel comfortable with his music being classified as 'fusion', it was the music companies and marketing honchos who had decided to do so. Allocating a designated spot on the shelf for the music lovers made everyone’s life (that is everyone other than the musicians) a lot easier.
The same holds true for other facets of our lives -- be it segregation by class, lineage, physical attributes or even intelligence.
Take for instance the so-called dog lovers out there. There are some who can spend hours raving about their pedigreed Great Dane and its great bloodline, and then in the same breath ranting about the menace of the street dogs in the locality.
This is what a child would say to all of them: “Street dogs are also dogs.” Not being clean and pedigreed doesn't stop them from belonging to the same species. Stop beating them and treating them as inferior. And by the way, it is only because of their pathetic living conditions and people’s constant apathetic attitude towards them that these emaciated dogs can get cranky.
