Denver offers its residents a large fenced park where they can not only can walk their dogs, but even wear them out by letting them run amok to their hearts content with their fellow canines. I stationed myself near the park’s centerpiece and trademark, a non-functioning full-scale fire hydrant placed within a cement circle. I watched and waited until this pair of dogs entered the hallowed circle to sniff the heady aromas there. As they warily circled each other and the hydrant, another pair surged into my frame at stage right, in full flight and full fight. The result: an image of a pair of pairs, defining the nature of the place, and its particular charms. Why is this image in my “Human Values” gallery? Because I see in it many of the same behaviors and attitudes their owners display: sociability, friendliness, competitiveness, wariness, aggressiveness, inquisitiveness, and enthusiasm. The long shadow of one of the owners at upper right reminds us that are our pets can be extensions of our own behavior, attitudes and values
