I wonder what this man was thinking about, when I tried to depict him. Feeling sincere interest to people, I discovered it was impossible to cheat people trying secretly photograph them, individuality under the question always knows he(she) is object of interest, even being surrounded by others, being in the group. As if they feel it, so we always know we are loved. They say the dogs always know who is afraid of them. Dogs catch micro movements and vibrations of our bodies, and also the smell of stress (distress) I think people are subconsciously sensitive about unknown for science vibrations of other creatures from the point of possible threat or incident.
