What my parents forgot to tell me?

I have such a great parents, they taught me all good things and molded me in to a better human being. I still wonder how they did all this, as they never told me specifically what to do or not to. All this happened may be by just looking the way they live and how they behave, because we spend most percentage of our time with our parents (in our childhood atleast). Not just my parents, fortunately the place where I was brought up had the same atmosphere. Everyone like a family, monthly get togethers, outings, games, cultural programs, what not. When a new family came in to those gates, they were welcomed with warm hearts and got help from neighbors. Everybody was equal just like a joint family. This is where our parents did wrong. We were very much a better individuals with better thinking in that small pond of ours. We didnt know what caste, creed or which native place our friends belong to. We didnt even know these words until we came out for higher studies.

Though we had our schooling everything outside our big family and that big awesome greenery place, our parents took utmost care, that we were educated in best schools in town. Adding to our misery, even our school friends and teachers didnt treat us differently based on our community or place which we belong, not even on basis of marks we scored (:P).

Once we all got separated due to our higher studies and different goals, we had to move to other cities. Then we got to hear the words caste, reservation, etc. And I was like, what are these and how did these kids get to know all this information. Why were we not taught inequality, communities, etc, etc? Why are these people hanging to some guys only and treating others differently? How do they fall in love with the same community of their's rather than based on their character. Life was hell for me! It was much better when I lived in great educated cities and people just randomly hangout with guys of same college or class or whatever. Out of this mist I found a few guys who never asked me what community I belong to or whatever crap and treated everyone equally and I still stay with them, even some teachers who are not just educated with high degrees but who have good moral values.
I still wonder how my parents raised me up in this way :)
