We meet people from our surroundings every day. Some several times a day. But we don't really know everyone, let alone because they know us. Neighbors from the same street, vendors in the nearby supermarket or even beggars on the side of the road. They are part of our environment, but not part of our consciousness. To explore our environment with the camera and identify people who are actually close to us is a small awareness exercise for the students. "I know you without knowing you" sharpens our powers of observation and draws attention to our unknown but familiar environment.
