How will you treat other people who ask you about your family?

I think if a person always asks questions about other people's families, it means that he is a gossip and boring person. When I face such people, I tend to face them with a very cold and distant attitude. I will use a machine perfunctory attitude to deal with his behavior of asking my family and tell her through my behavior that I don't want to talk to him. Generally speaking, I will face others' questions about my family with a very cold attitude.
