Strangers' faces, covered with scarves and hats, unwittingly enter the realm of anonymity. The public image is no longer about impressions, as comfort and survival push their way to the forefront.
Perhaps due to this inherent anonymity, most people in the winter walk alone. With shopping bags (and sometimes a dog or two) in tow, strangers pass each other with their heads down. This lack of public kinship can sometimes dehumanize others, but most of the time a collective understanding is felt. We're all just trying to get somewhere better.
