I mean, it's difficult. People need to know these things. That's just what India is like. Their idea of boundaries is different from ours. You only have two options: be rude and say none of your business but I'll doubt you'd get away with that or just be honest with them and tell them the truth or some version of it. Mostly, you have to treat people according to their station. Don't answer anybody who is "beneath" you in age or social status because they have no business questioning you. If somebody is in a position to interrogate you, then you do have to treat them respectfully and answer them. Sometimes, I just don't answer or give an indication that I am uncomfortable with the conversation. In India, it's understood that you don't have to answer every question. They just throw a lot of questions at you and your silence speaks volumes. If you don't answer, they know they've hit an uncomfortable spot and that is an answer in itself. When she asked about your dad what did you say?
