Street is the common place. Everyone is allowed to use it. The affluent use it as little as they can, poor as much as they have to, usually a lot. Winter in the time when city reveals its many secrets that go on all the time but are not as obvious as on the cold bitter days. Invisible in warm weather homeless people suddenly get into the front line of attention.
Homeless person has no choice.
We usually have a choice. Twilight is changing into the night. Cold wind is picking up and scattering the snowflakes in all directions. You hasten your step to get where you are going to get out of the cold. Middle aged woman dressed in a worn sweater is standing on the corner of the street.
