Fifty years ago, the small town in southern Spain where the author lives was much smaller, with mostly old buildings and no modern structures. Transportation has also changed significantly over fifty years - there was once a train station but now no railway, and most people did not own cars but traveled by train or bus, whereas now there are many roads and a nearby motorway. Additionally, fifty years ago there were not many job opportunities in the town, so the author's grandparents did not live there at that time.
