The only reason why people said "not to kill cows; they are holy, cow is like a mother, its a sin, its our national animal" and all that $hit because cow was a very important source of food in ancient times. Like we follow all those ancient craps like "two people should not leave a house on the same day", it is similar to that... How are cows holy, and not buffalos? What makes them "holy"... just because they say its holy doesnt mean its holy. And some people were saying its our national animal. What the hell is a national animal??? Its not a endangered animal!!!! WE should learn to accept facts, not follow a something blindly, like most of us (Nepalese) do! Jai Nepal!
