I have jotted down my reason for gender in my first post that it helps others to address ,a poster to which they are posting replying , using the right gender.
Some times when you call someone bhai that turns out to be nick of a bahan and other times when you call someone auntie , it turns out that the auntie is an uncle.
That is it .
You are right , mujahay kisee say rishtay dari nahi jornee , but I want to be polite , and I guess many other guppies and guppan will second me on that, thats all.
