Why U Not call your friends by their original names?

when we call our friends in our collage its not by their original names, but...
OK instead of giving theory let me give u example,now when we yell out name 'सच्या' it means sachin is called.
on this issue(such a cute word in English) i want to focus today...
i am taking to my friend and sa soon sa my call ended my father ask me "Why U Not call your friends by their original names?"....

actually i  have answer but not acceptable!!!!!

in my friend circle we never called each other by their complete name .but we twisted their names and make them   2 SHOT PRONOUNCEABLE.

now what that mean is ..

we call sachin as  सच्या

vinay  विन्या

sumit सुम्या

umesh  उम्या


and this goes on ...
we belive that only calling like this we actually communicate properly.
this does not mean that we are respecting their mother and father's feeling which they have from their son while keeping this name to their child.
but this is our ownway to call... and we proceed like this only.
someone said me that you are not people who know to give a respect to other...(hahahaha)
आता ह्याला काय बोलणार .

मला वाटत अपभ्रंश केल्याने नावाचा अपमान होत नाही तर त्यामुळे मैत्रीची नाती घट्ट होतात .
आम्ही मित्र कधी सुद्धा एकमेकांना पूर्ण नावाने हाक मारत नाही .जर असे एखाद्याने केले तर तो शीवी खायल दुसर काय.
नाती हि काही formality म्हणून बनवायची नसतात . आणि आम्ही मित्र असेच आहोत .संस्कार म्हणजे भाषा नाही ,तर संस्कार म्हणजे एकमेकातील समंजसपनाची जाणीव होय .
एकमेकांना आदराने वागवण्यापेक्षा ,एकमेकांना प्रेमाने वागवलं तर जास्त चांगलं अस वाटत .

तुम्हाला काय वाटत???
