Smiling Man And Suspicious Man

Some people interested in me and my SLR camera. On the other hand, some people took a dim view of me. At this time, I was taking some photos of a man standing in front of me. He was smiling and seemed to be enjoying being shot.

Yet I felt someone looking at me at the same time. And I found another man looking at me with a suspicious eye from the behind. I didn't know why he made such face at me. Maybe he also wanted to be shot like him.
