One of my travel hobbies is to take photos of people I see around the world. I do not know these people. Rather, I take pictures of people who are posing for others, and I collect images that make it appear that these folks have posed for me. Many of these pictures were taken throughout Asia, but also many other places. In at least one case, the people were posing for themselves, as when I saw some young won=men setting up a remote tripod on the Hong Kong waterfront before standing before the camera and leaping in the air in unison. I call this hobby People I Don't Know.
