I walked by this man with the bigger than normal either Nikon or Canon digital camera, one of the types I have my eye on, I rather said hello; however he was not so interested in being friendly.
He was grimacing, searching for the photo. Now, to me the grimace needed to be left at home. Smiles make people relax, having fun is ok, however a photo appears when it appears. Of course you can if you work hard, try very hard, stage photos, make the photo happen.
I was being sneaky, taking a photo of the person taking the photo. This is a little complex to do, I am doing a test. Is this person really paying attention to the world around him or does he miss me completely trying to take his photo.
