Hindi language is crude, and has unintelligent manner of speech, it conforms to what is apparent from the local culture,where everything about the region is crude,vulgar,insensitive,disrespectful ,dull witted,very inelegant . Indian people will talk and act more civilized if they discarded Hindi languages as whole, IQ will rise by a point .
For comparison take Korean language for example :
Come here is, ili oseyo ,it by includes "please" by default,it shows Korean culture for respect,humility and civil attitude.
Japanese : Koko ni kite kudasai- come hear ( please make this effort).
My folks take a step further,we refrain to even asking people to come here,
we say :Leng bi ja biyu asond-a - please make tilt(instead of come) this side. (Ja is an unique term indicative of "i humbly" , attached behind any noun,verb as a preposition, it can't be explained in any other language.)
All these matters,they determine how society operates and how people view the world.
