If your image was in a magazine, I would have kept turning pages without even a slight pause. Sorry. I am commenting only because you asked for comments.
kentay, 171fan, angel, stereobox, and most of all the good doc: thanks once again for the feedback - I asked for it, and I got it!
However, I did not expect such a polarised set of feedback, you people either liked it... or not!
Anyway, as with a lot of things, the significance or relevance of something usually become apparent only to the person who is looking out for it e.g. a person in that mood or have recently experienced something similar.
Just to complete the post, this image was taken in Lisbon in the middle of the afternoon. I was passing by this old man sitting there while enroute to another tourist attraction but did not have time to shoot him. This shot was taken on the way back while passing by the same place - imagaine him having sat there for one hour!
