Three Worlds in a Picture Frame

I found the moment I took this picture one of the most interesting ones during our long walk of Bilbao's 'Casco Viejo' (old part of town) There are three men, they fit in a picture frame; they are so close, but so far away from each other. They form three generations, they have lived completly different worlds; however, they share the same moment in life in this photo. Each one of them is interested in his own world, living his own reality, they only share the space in this picture. Time, space, life... the world.
