In most of our social gatherings I find that the men and women "self-segregate". Even if everyone can sit together, the women will start off in the kitchen then move to the family room and the men stay in the living room until it's time to eat.
Even at weddings or formal gatherings where there is seating arrangements by family, the women end up sitting together and the men go off into their groups - to phir sirf naam ka hi mixed gathering hota hai.
So you think women on their own move separately and men do the same..
