Noblebeast makes an excellent point that only a still photograph could best present that kind of situation.
I still maintain, however, that this particular image is not complete within itself unless the viewer has additional information, or is already familiar with the situation. Taken out of context we don't really know what it represents, although so far the consensus of the responders on this forum is that it somehow represents children who are old before their time, and have lost the optimism of youth. That's an awful lot to read into a single picture with no real information on the underlying background.
I'm reminded of the quotation by Walker Evans when asked if a photograph could ever lie, his answer was, "they always do."
