Please sahib, explain the customs of these exotic people of the Orient of which you are an expert. Regale us with tales of your service with the British Raj among the unenlightened Hindoos
no I contributed my own relevant experience to the conversation. You say that Indians often casually call people sir. I have grown up in an area with a high proportion of Indian immigrants and known and worked with many both raised in the UK and recent immigrants and have not known them to call people sir. My point being is that it is clearly a more complicated cultural thing than you were saying
Tell you what next time I'm talking to an Indian I'll ask about it as they should have a better idea of their own culture than we have
As an indian , born and living in india , I feel indians only use sir under subjugation , however sometimes its out of respect ( like calling a scientist or someone sir out of respect for their contributions)
